I do a bit of photography and have a colour corrected wide gamut monitor I use for retouching.

To my eyes, when looking at the same photography on both devices, the new colour temperature is much closer to 'correct' than the old one was. Not perfect but much more preferable to me.
[Nexus S General] slowz3r:
so maybe all the complaining people have been doing is just their eyes not used to what the screen "should" look like
[Nexus S General] mhaedo:
That is 100% correct. My girlfriend is a professional photographer and she even commented on how much better it looks.
[Nexus S General] ChrisJ:
I know that when I first bought my Datacolor Spyder colorimeter to calibrate my monitor it took a while to get used to the results. Much less "in your face" than before, but much closer to natural.
[Nexus S General] wko668:
I exchanged my first Nexus S because the screen was too blue/purple. The second one was slightly less purple. But the new color profile got rid of all the purpleness :)
[Nexus S General] 2012iawait:
agree.... i think this might improve the battery life too.
[Nexus S General] woaibolin:
google fixed ns's color too much...

though grey does not display as purple any more,white displays as a bit yellow now,what takes ns's sharp display away.

on modaco r11 "2.3.2" and the colors are awesome , i had the purple tint on dark gray areas but its all gone now .

can someone compare this with the colors on 2.3.3 ?
[Nexus S General] WingnutStrikesBack:
I like the new colors it looks now great!!!
[Nexus S General] profets:
I noticed the colour difference immediately as well. It actually felt weird to me, I was really used to the purplish colour in the UI. Feels very grey. Not complaining though if this is how it should have been, but feels weird.
[Nexus S General] shikem:
I for one do not like the new colors. They look too washed out and gray.
[Nexus S General] Teknojunkee:
The Crispness is gone. Whites are now yellowish. I am not a fan. I did a comparison with a friends NS side by side his with 2.3.2 and mine with 2.3.3. and there is a difference and 2.3.2. looked better. This could be "the correct color" as has been stated but that does not mean it looks better. I have never noticed a purplish tint before and even looking at my friends NS with 2.3.2. I still do not see it.
[Nexus S General] profets:
Same here. Looking at it again (2 Nexus S side by side) the one with 2.3.3 really seems washed out.
[Nexus S General] jeffdgr8:
I did notice an occasional purplish tint on 2.3.2, but mostly from different viewing angles, less so when looking straight on at the screen. It never bothered me. The overall color scheme was also a bit cool, with more blues coming through. I've read that because blue LEDs in AMOLED screens wear out quicker, often they are overemphasized at first and will fade over time. I thought this might have been the explanation.

I definitely noticed a color change after updating to 2.3.3. At first it was very bothersome. The colors do seem to be washed out and the whites seem just a tad yellow. But I can see how this may be more accurate as the previous color scheme was overly cool. Maybe we tend to prefer a cooler color temperature. The new one will take some getting used to. Blue is a "comfort color" after all.
[Nexus S General] dinan:
Blue appears brighter to the human eye despite the actual lumen output being similar. It's like those custom bulbs that some people like to put on their honda civics or whatever, the blue/purple looking ones. Yea they "look" bright but they actually output less light than the standard yellowish bulbs.

Anyway, being an avid photographer and spending hours tweaking my plasma TV's colors, warmer colors are more natural to the human eye and most people jack up the blues to make things look more contrasty or sharp, which in my opinion is too harsh and fake. Even the iPhone 4 screen is tinted blue to make whites appear brighter. Then again, some HTC screens are so red tinted it's ridiculous, so in the end, download the color calibration app and tweak it according to your liking.
[Nexus S General] slowz3r:
i would say the voodoo fix isnt as "extreme" as 2.3.3
[Nexus S General] benrees21:
I like the new colour scheme but the screen is less bright (I have it on auto) and i could always turn it up but i prefer it on auto as it saves a load of battery. The old colours were more crisp but un-natural, why don't google just add a few schemes into the display menu for people to choose what one they want?
[Nexus S General] princeasi:
As far as my phone, the whites are white. No yellowish tint at all. Not to say that other don't have that issue. My current NS had a "slight" purplish tint problem so I guess this update balanced the colors better than other NS's with worse purplish tint issues.

[Nexus S General] kenvan19:
I agree with the people who are saying that it is more than likely just the fact that people are used to stuff not looking right. I've done a lot of color calibration and the one thing people always say is that it looks dull but then you realize that pretty much every screen you look at nowadays is specifically tuned (the blue is tuned way up because the human eye reads very light blue as pure white and manufacturers know that) to make you think their screen is brighter and looks better without actually making it brighter or look better. So when it is tuned to look like the real world, ie more natural and you're used to it looking very blue its going to look the opposite of blue which is yellow. Hence the yellow tint.
[Nexus S General] irenic:
i never had purplish issue, well maybe there is, but not that obvious to become an issue to me..

now my nexus S display is on par with my desire hd. super amoled vs tft lcd? :p

[Nexus S General] Nexus-S:
The new greyscale gets a thumbs up from me. It is definitely more accurate than previously.
[Nexus S General] JRG1392:
Why don't they just put it in the settings so you can pick your own?
[Nexus S General] tonyt3rry:
I was thinking that to be honest, It will help all the whiners. I have not had the ota yet but if professionals are saying its better and google are then someone must be right. Maybe open the doors to custom color schemes for people wanting to save battery or make the display really good to thier liking
[Nexus S General] seriouslyjeff:
color calibration app? what is this you speak of kind person
[Nexus S General] Nexus MC:
I haven't received the OTA update as of yet but was curious of this color change and wanted to see it. Checked Android Central and they posted a comparison.

It does looks washed out and warmer. But the gray looks more truer.
[Nexus S General] kenvan19:
@Nexus MC Ya that is definitely more natural. You can see definition in the dark greys as opposed to them just looking black which is one of the things to look for when comparing contrast.
[Nexus S General] MadFerIt2011:
I wasn't having the purple tint issue to the degree as shown above.. So I'm getting quite a bit of yellow tint thanks to this update. Even at full brightness it's noticeably yellow, and white is nonexistant at low brightness. It's that bad.

Suffice it to say, I hate it.
[Nexus S General] JAguirre1231:
I like the new colors, but I think it'd be beneficial to look at a Nexus S running 2.3.2 side-by-side to one running 2.3.3 to really get a feel of how different it is.
[Nexus S General] JRG1392:
The main problem is that each samoled screen isn't identical, some are purple, some yellow, and some lucky ones are even white. That's why I think it should be in the settings so that people can configure their screen to make it look the best, that way nobody can complain.
[Nexus S General] mingkee:
Here is the comparision of nexus one and NS after 2.3.3 update.

I made the exactly same conditions (brightness, wallpaper). I personally perfer color on nexus one as the blue is more like blue, NS on the right is more greyish.
[Nexus S General] kenvan19:
I would say the blue on the N1 is actually more reddish and I still maintain that the new SNS color scheme is very natural. I love it.
[Nexus S General] princeasi:
Grays are supposed to be gray no matter what the brightness settings are. Before the update the grays were purplish, reddish, maroon, etc however you want to call it. Google has corrected this problem. I see there are plenty of people who disagree with the change. Personally I'm glad Google fixed this problem. Grays are not supposed to be purple under any settings, point blank!

this is really tempting. i found a used one for really good price and its almost brand new with no grid pattern and no dead pixels. but at low settings the the colors are in pink. i wonder if i buy it, and update, the pink will go away ?

what if the nexus S i have didnt have any pink in the first place. and then updated, will it get "grayer " also ?
[Nexus S General] brumwald:
Now I'm a display junkie and succer for accurate colors, there is no way a TN-panel gets into my house (laptops are excused) and all monitors are hardware calibrated.

I really value accurate colors.

But, on a mobile phone there are other aspects of the display that plays a huge role in how the phone can be used.

After the update the colors seem much more washed out and the brightness seems to have been lowered (whether thats just a side-effect of a warmer color temperature I don't know, but if it is then that just means that the old temperature was more battery-efficient (and that sure is of utter importance)). Two days after the update I still "wow" every time I turn on the display because it's so washed out.

And thats perhaps one of the most important things to point out, for whatever reason the display is perceived as less bright and the perceived contrast is much lower. This affects the overall usability of the phone, text is harder to read and this will be particularly apparent when the summer arrives. And if it means that you will have to turn up the brightness on the display well then thats a disaster by itself.

And that is something that I really liked with the Nexus S, not that it had the most accurate colors but that the contrast and brightness was unparalleled and thus that it was one of the very few phones that actually could be considered usable in light conditions. Not so anymore? :(

Yes, the colors might be more accurate but the overall usability is worse and if you take into account that I perhaps spend 0.001% of the time watching photos it's not a huge issue that the colors are a bit off. Also since others seems to have had much more prominent purple issue I guess that means that I have a much more prominent yellow issue...

And do not compare this to a desktop monitor... The conditions for how a desktop monitor is used are very controlled, it is certainly not viewed in direct sunlight.

If absolute color accuracy was the goal then we would have to limit ourself to one set of environment and hardware-calibrate all displays manually. This is not such a big problem for desktop monitors but for a mobile phone it's just ludicrous. Sure the line has to be drawn somewhere and thats of course up to debate. I for one dislike the changes made in the 2.3.3 update.
[Nexus S General] Raver27:
Um from pics I've seen I'm confused, what color is the notification bar suppose to be????
[Nexus S General] JRG1392:
Standard 2.3 with no mods has a black notification bar.
[Nexus S General] Raver27:
Thanks, I'm thinking I'm never going to update mine as long as Google sticks with this color scheme
[Nexus S General] CB620:
you should try it you can always restore back to to your previous build.
[Nexus S General] mingkee:
How can it be done?

I may get rid of my NS if the color scheme stays this way. Now the screen looks like covered by a milky screen protector. This is pretty obvious when I watch TV channel in 4:3 aspect in Slingplayer. It used to have "all black" frame around the video, but now it turns grey on left and right, and stays black on top and bottom. It looks wierd.
[Nexus S General] mingkee:
This is another comparison pic taken under the dark:

I still prefer the screen on nexus one after 2.3.3 update as the contrast looks much better (look at winamp widget as well as menu widgets. They're supposed to be dark grey).
[Nexus S General] ghost010:

[Nexus S General] iseedeadpeople:
I guess this color issue is really subjective now not a Google update issue and the fact that no 2 display are identical even on computer monitors these are mass produce so it could be a factor too, for me the other fixes that came along the update outweighs the so called "color issue" so I'm a happy camper...

[Nexus S General] MadFerIt2011:
Again, not all SAMOLED are created equal. So while it is a "fix" for some people (in that whites are now more "natural" rather than flourescent-like), on some devices it will cause unnaturally yellow whites and overall unnatural temperatures.

We should have "options", not just a fix that works for some.
[Nexus S General] MadFerIt2011:
Btw, I just installed the Voodoo kernel for 2.3.3 (for stock ROM) and the included colour profile is pure win.

Fixes purple tint (pure grey now) and no yellow tint. Next version should let you choose between stock 2.3.3 colour profile and the Voodoo profile on the fly. Best of both worlds :).

To me it seems that i went from an LED tv to an LCD tv. I don't like it at all, i would prefer it broken than fixed. But, I am gonna try voodoo's color improvements and see if i can get something good. Other than the whole color issue, it seems like it runs smoother, i like it.
[Nexus S General] kenvan19:
To anyone who thinks there really is an issue here is what I want to see: Get a sheet of blank white printer paper. Navigate your phone to Google.com and hold the sheet of paper over the google logo so you see only the white paper and the white background of the page. Tell me how different the two colors look and take a picture. Post them. I'd bet they are pretty damn close because I know the colors on my Nexus S and my wife's after I updated both to stock 2.3.3 were very natural looking. What most people call bright on the other SGS devices is actually just very blue which the human eye reads as very bright white. Its not. I

Here is another fun test:

Navigate to this image on your phone: Picture on 2.3.3 and see how much detail you can see. Now revert back to 2.3.2 (just flash any current ROM) and do the same test. Guess what? You won't see near as much detail. What you think is deep blacks actually should be nuanced greys but because of the overly blue saturation it appears to be black.

One final fun test: If you have photoshop open a new file and make it blue. Now invert the color. Guess what color comes up? Yellow! The same supposed new tint of the screen.

Claiming the yellow tint is a bug or something of the sort is false. I can see the difference between the two screens; I held my wife's 2.3.2 phone next to my 2.3.3 and I saw the difference but I also know that what people are calling overly yellowish is actually just more natural. Now, if people dislike that they are more than welcome to try and change it for themselves but I would rather have an accurate display on my phone that shows minute details as opposed to having one that looks a bit brighter while not actually being brighter.
[Nexus S General] Jayrod1980:
I've noticed that there is far less banding now than before and I thought the screen on this 6th nexus s was the best I'd seen so far prior to 2.3.3. I never had a huge amount before the update but its entirely gone now and colors are much better. Took me a bit to get used to not having all the blue but I love the new color on the update. I had barely any pink in low brightness greys and I've had a voodoo kernel on the phone with the color fix. The fix corrected the grey issue but I like the color on this new android version better. Its as kenvan said, there's much more detail now. Please don't change it back!
[Nexus S General] tonyt3rry:
Just updated via link thought lets go for it..... screen I think looks the same if not better the boot screen for some reason looks better it stands out more I thought it looked blocky the homescreen indeed looks brighter on full brightness but I never put full bright on I agree greys look nice but again I can't see The difference people are moaning about SERIOUSLY. enjoy your nexus s I AM
[Nexus S General] princeasi:
For those that hasn't done the upgrade, you guys should download this free app from market called "Screen Test" by Amberfog. Tap the screen a few times till you get the gray colr bar scales. If any of them are slightly purplish than your screen is not color balanced correctly. Every bar should be gray from light to dark!
[Nexus S General] mingkee:
I think the best solution is to get screen capture application and cap several screens and put them on your computer and compare.

Google should put more detailed screen adjustments like Galaxy Tab (contrast, gamma, tint) to let the user to adjust to the taste, and put a reset (or default) button if it's messed up.
[Nexus S General] kenvan19:
The Galaxy Tab is running TouchWiz and the a lot of the apps on it are Samsung Apps.
[Nexus S General] ll_l_x_l_ll:
again. no one answered my question.

originally, there are :

1- normal white screen on high birghtness + pink gray in lower brightness

2- yellowish white on high brightness + pink gray in lower brightness " god help the mfer with this screen "

3- Normal white on high brightness + normal gray in lower brightness

4- Yellow white on high brightness + normal gray in lower brightness

my question, if 2.3.3 applied to all those screens. will the results now be equal to everyone regardless which screen he used to have before ?

because i dont think it will be all the same. it might have fix the pink issue for example with people who had it. but for people who didnt, the gray now its somehow "grayer" which will cause a bad color accuracy.
[Nexus S General] mhaedo:
A screen capture application would do no good. It would capture the same image regardless of the kernel and display drivers. The image remains the same, the way the image is displayed is what changes. If you took screenshots with 2.3.2, 2.3.3, and voodoo color, they all all look the exact same on your computer.
[Nexus S General] :
Google is so sloppy, this is something that should have been addressed when launching a device, not two months after users have gotten accustomed to things.
[Nexus S General] ll_l_x_l_ll:
agreed. the only way to compare is 2 nexus S. one with the new update and one with the old.

the only way i see this is 2 couples that are so in love they bought the same phone --_--
[Nexus S General] princeasi:
I think this will only address the the color temperature issue specifically(purplish, pinkish, reddish etc). As most of us know, the quality of the display varies with each NS manufactured. One NS with a the purple issue may not be as prevalent in another, in saying that, applying this update to both NS's will fix the problem but the display will still show different between the both of them because of how they were manufactured.
[Nexus S General] ll_l_x_l_ll:
well.. at the end of the day, if my gray after the update wont look as good as the other phone " better gray " then we are back to the same hole.
[Nexus S General] silverwolf0:
This bodes well for all Android superAmoled phones, present and future. The blue tint on white backgrounds is very apparent on all the youtube videos I've seen from various review sites, as well as personal experience with a Samsung Wave and Vibrant. Unless none of the reviewers got lucky enough to get a white/yellow screen that some users have reported, I would wager most* of the superAMOLED are blue and this fix flips the switch, helping most and screwing a few others.

But ultimately I don't think the screens really vary THAT much and it is really down to individual perception, some people more sensitive to blue and others to yellow. Someone needs to start a petition for multiple color profiles in Android or color controls. Every screen from TVs to laptop screens can be calibrated. Mobile devices need to get into the game. People actually watch movies on them now.
[Nexus S General] benrees21:
I've always said there should be multiple colour profiles because then everyone is happy. Don't know what it would take to implement that though.
