[Nexus 5 Themes and Apps] bleuxeon:
I realy respect your work so please take no offense, but I wonder how you can give ton of users, sprayed all over the world, a unique and single calibration formula.

You have opened the door for calibration and for that : 1 billion of thanks but plz don't make kids think that your numbers are universal!

-Every screen pannel is different from the other even if it comes from the same batch.

-Color calibration is also linked to the time the screen was on, the external temp, the internal temp of the phone.

- last but not least : the screen age. Color calibration does NOT remain the same month after month, and that particularly true when screens are young.

I hope it would help some of you, and maybe..the OP ;)
[Nexus 5 Themes and Apps] RankWinner:
Could anybody give me a quick guide to calibrating the colours? I've looked around but I couldn't find anything that really helped (then again I am vast at finding things).

I think I get the basic idea of looking at the gamma test and seeing where your colours are, but I don't know what variables so what.

So, if my red is at 1.9 I would need to move it towards 2.2 by making the red brighter (?), but what values do I change? Is there a list of what column and row changes what?

What values would I change to make my red gamma increase, would I change just things in red+ or red-?

I'm sure this is answered somewhere but I couldn't find it...

P.S. The red thing is just an example, mine aren't off by that much.
[Nexus 5 Themes and Apps] italia0101:
This is exactly what this thread is trying to find out.
[Nexus 5 Themes and Apps] RankWinner:
Well... ah. Fair enough. Whoops.

Is there a list of what people have found out? I've only skimmed through a few pages of the thread so far.

[Nexus 5 Themes and Apps] tkoreaper:
You want to adjust the values in row 3 column 1 for red. This allows you to raise the gamma. Row 2 column 5 affects gamma as well.

It is.

I can't notice any changes to color with Faux's modifications in the second post....
[Nexus 5 Themes and Apps] PhantomGamers:
Yeah I don't either really, it's very subtle... but if you check the gamma values with like Display Tester it should be much closer to 2.2 than stock.
[Nexus 5 Themes and Apps] MontAlbert:
i had the same issues- just took set on boot off and rebooted- tried the ones from Moh_jay on the previous page

http://xdaforums.com/showpost.php?p=48109047&postcount=231 (well, my previous page as i have more posts per page in my settings) and not only were the gamma settings very close to 2.2 across the board photos didnt look messed up either:

"Well I got a new setup that isn't completely perfect but yields some nice results. Only changing the values on 2nd row 5th column, red + = 100, red - = 107, green + and - = 120, blue + and - = 122, white point = 29.

My results with Franco kernel R15 without modifying anything:

Grey 1.8

Red 1.8

Green 2.0

Blue 2.0

Yellow 2.0

Cyan 1.8

Magenta 2.0

I tried all of the other recommendations, and even though the gamma went closer to 2.2, when watching YouTube videos, faces got real weird, as if a picture would be shrunk in size by "generalizing" colours. Is there something wrong with my display? I do know that all displays are different, but a range from 1.8 till 2.0 on "stock colours" and this weird colour on faces with other configurations does seem a little odd to me. I included pictures of the "stock" settings.
[Nexus 5 Themes and Apps] ChazzMatt:
It looks like "posterization" (also called "solarization") -- as if some special effect is being done to the pictures.

sort of like this:

Do you think messing with the 3rd row of numbers causes this? It seems to have started happening when we moved down to the third row of numbers.

ah, someone else has the same theory!
[Nexus 5 Themes and Apps] Moh_Jay:
Nope its not restricted to third row. Seen it happen when testing values on first and second row only.
[Nexus 5 Themes and Apps] ChazzMatt:
this guy has the same theory:

I restored backup from a couple of days ago when I had just adjusted the first two rows (earlier settings). Everything is fine. I'm going to hold off on that 3rd row until we know more.
[Nexus 5 Themes and Apps] Moh_Jay:
Here are some settings that improve on stock colors but aren't 2.2 meaning extremely miniscule banding and no red looking greys, while getting rid of the yellow tint. (First number = first row column 1 and second number = second row column 5) Red + = 0, 106 Red - = 0, 107 Green + and - = 70, 120 Blue + and - = 77, 121 White point = 32.

3rd row is banding control. This is very similar to my Nexus 4 Advanced Color and Gamma Gradient control options. Many of the 3rd row controls adjust the banding of a specific region and you have to VERY CAREFULLY balance them otherwise visible banding will be shown.

about thinking patterns :)

for those who are looking for more saturated colors and deeper black, say good-bye to gamma 2.2

the more saturated colors and deeper black with more contrasts ly in the higher gammas.

i have a setup between 2.4 and 2.6 gamma and it looks similar like franco's former tweak

for those who remember and miss it.
[Nexus 5 Themes and Apps] DanRyb:
Could you share your settings? I am desperately trying to re-produce Franco's r14 color! The changes posted here are certainly better than stock but still too warm for my tastes.
[Nexus 5 Themes and Apps] ChazzMatt:
Sure, gamma 2.4 is even better.

The default on these phones were 2.0, which is why they looked so washed out.

I only wanted 2.2 because it was better than 2.0. But some movies are shot to be watched in 2.4.

Hey, I found many colours differences between flashing hammerhead-faux123-004b06.zip or set ideal Gamma 2.2 with the app.. Why? I want to set hammerhead-faux123-004b06.zip values on franco kernel? How I can do it? Help me please...
[Nexus 5 Themes and Apps] fireproofrev:
thank you for the information that higher gamma makes the colors more pop. I have played around with the settings and got about 2.6-2.8 gamma overall without red touch in the grey. Blacks are deeper and colors more saturated. Here my settings (I know that are not ideal values for accuracy but I like it so far):

RED+ 0/95/115

RED- 0/100/110

GREEN+ 60/110/124

GREEN- 60/120/124

BLUE+ 85/125/128

BLUE- 85/125/128

WP 26

Maybe it is a little bit too dark with white point 26, I will keep playing a bit around in the future.

Can maybe anyone explain how negative and positive values are in touch? What does positive and what negative?

EDIT:

Has maybe anyone figured out what the other values are good for?

It would be nice to have an overall progress with the reverse engineering so developers like faux can make an cool display calibration tool with sliders and better naming for the values. Would buy or donate instant when some nice tool is ready :D
[Nexus 5 Themes and Apps] resynx:
These are nice! :D Had a bit of a red tint on some grays / white so I changed the Red- 3rd value to 115 and it fixed it a bit more for me :good: Thanks! :)
[Nexus 5 Themes and Apps] fireproofrev:
For me I only see a red tint in the grey gamma test background. In all banding pictures i can not see any red tint in the greys so it should be ok and related to the gamma test.
[Nexus 5 Themes and Apps] ChazzMatt:
Yes, that's better. Comes in at 2.3 - 2.4 across all colors (some 2.3, some 2.4, some too close to call). But colors pop more and blacks are crisper. Thanks.

Also, applying say the 0 value doesn't do anything? Do I need to apply 3 times for Red- ?

I found some really nice looming settings so far mainly only lowering the values on row 4... I'll post my findings when I get to a PC tomorrow... I'm just adjusting numbers and trying to remember the changes each one makes but it's basically a guessing game and lowering row 4 seems to give me nicer contrast and more saturated colors... I dropped most by about 20... More details once I dial it in better...

After you hit apply, you have to turn the screen off/on to see the changes...

[Nexus 5 Themes and Apps] ChazzMatt:
any banding with this?
[Nexus 5 Themes and Apps] fireproofrev:
On real Picutres, system-icons and in the DisplayTester I can not notice any bending.

BUT I noticed just a little bending when you have an (In App) shadow effect on greys. (I think it is related to the RED+/- value in row3)

Abouth the 4th row, a user here told to lower all values in row 4 to geht higher saturation. First I have read it wrong and I have raised all values by 20. This gave me an extreme weird banding on darker colors. Maybe I will also try to lower the values like the guy here said but I think row4 adjustment (without knowing the values exactly) will result in an extreme banding (not overall just some colorranges). will do some tests.

I've been reading anandtech's super in-depth/technical review of our beloved n5. Brian summarizes that "Nexus 5 has the best calibrated display I’ve seen so far in any Android handset.".

I'm a bit of a noob when it comes to the screen (gamma, color reproduction/calibration, banding, etc.). Reading the review, however, I'm a bit confused as to why everyone is going to such great lengths to change the look of their screens, if someone like Brian is suggesting that the screen is great the way it is. Is it a matter of preference? I'm just curious and hoping that someone could provide some constructive comments. thx.

[Nexus 5 Themes and Apps] DanRyb:
Is anyone here having success with cooler/bluer colors ala Franco's r14 Kernel? Most of the ones I'm trying (and maybe it's my screen or just me) still seem awfully on the yellow side. Less yellow than stock but still not quite as cool as what Franco had. Or what values would I change/pay attention to more to get a bluer/cooler look? I tried playing around with Blue+ and Blue- but admittedly don't know a lot of what I'm doing lol.

I actually ended up going back to Franco's r14 because the "normal" Nexus 5 colors bother me so much but apparently whatever Franco changed wasn't supposed to produce the colors it did and that's why he reverted so I am a bit concerned of any possible long term effects and I'd like to update eventually, just so bothered by the yellow! :)
