Talk:Truecolor

message: I'm curious as to what hardware, specifically, utilizes the extra byte in 32-bit truecolor for the implementation of transparency. I've always been under the impression that 32-bit depth in the context of graphic display is exactly the same as 24-bit depth, with the extra byte purely for padding. An actual pixel (on the monitor) cannot be partially transparent, so if the extra byte is used for this purpose, it would have to be a capability of the video card.
Now, this is distinct from 32-bit image files (such as PNG), which clearly (no pun intended) may have an 8-bit alpha channel; this, of course, can be used to layer images and achieve transparency; however, the current article implies that GUI effects involving transparency somehow take advantage of the extra byte. Is this true? Do newer video cards utilize the extra 8 bits? -- Wapcaplet 19:06, 19 Oct 2004 (UTC)

message: whilst that image in its origial form may have contained every color in the 24 bit RGB space, it was totally mangled to the point of being basically meaningless by the scaling process, also the image description page has no infomation on how the colors are laid out. Therefore imo placed directly it mislead more than it added any usefull information and even as a media: link to the proper image its value would be minor at best.

message: I believe that this particular term (as a runtogetherword)originates with the X Window System.  X servers may implement multiple color models, called "visuals", which are given a type.  This article describes the models known to X as TrueColor and DirectColor.  (The difference between the two is that DirectColor visuals send each color component through an application-defined mapping before displaying.  This is analogous to StaticColor versus PseudoColor, where the color map in the former is fixed and in the latter can be changed.)  In any event, that would put the origin some time between 1984 and 1987 if correct.  Does anyone have a citation antedating 1987?  121a0012 04:21, 16 February 2006 (UTC)
thread_title:  Terminological origins 

message: For anyone who wishes to enhance the article visually, there's a series of image I've uploaded to the Commons:
* :Image:Park-TruColor-24BPP.png (24-bit truecolour reference image)
* :Image:Park-HiColor-16BPP.png (16-bit highcolour version)
* :Image:Park-HiColor-15BPP.png (15-bit highcolour version)
The thing is, I don't know how to incorporate it into the articles, because 1) I don't know how to fit the images, even as thumbnails, without wreaking havoc on the page layout, and 2) when presented as thumbnails, the scaling resamples the images, thereby rendering them useless for the colour depth demonstration unless the reader follows the links to the full-sized images. --Shlomi Tal ☜ 20:32, 24 June 2006 (UTC)

message: "The human eye is popularly believed to be capable of discriminating between as many as 10 million colors."
Uhm, what is this rubbish?? It is unsourced and uses weasel words. And, furthermore, my eye, which is hardly very sensitive, can definitely see more colors than 24-bit color allows. 4.242.147.168 23:15, 28 January 2007 (UTC)
