Monitor color resolution

A correct perception of color is very important to use and navigate this site. The way your video system is configured heavily impacts the way your browser handles colors, so here is the list of the more common display color resolutions and the kind of visual results you can expect from them:

True color

(24bit or 32bit - 16M colors) This is the right color resolution to fully appreciate this site on-screen colors. Everything higher than 24bit resolution is fine but from a practical point of view is just nonsense.

High color

(15 or 16bit - Up to 64K colors) You'll loose some color definition but you can still have good results. Probably if you compare a monitor using this resolution with a 24bit counterpart, you will not be able to detect any great difference. Monitor settings play a much important role in digital color perception.

16 or 256 colors

You will not be able to correctly see on-screen colors, they will tend to melt together and look all alike. You can anyway use all the color numeric data resulting from the use of the different site services.

Check your color resolution
Take a moment to check how colors are represented by your video/graphic system:

All the color tables (below) look different:

Your system is able to visualize 16M colors. Keep in mind that the color difference between the first 2 tables is very subtle.

The 16M and 64K tables are very similar:

With a 15/16bit video card you should be able to detect dithered colors on the 16M table.

All the tables have the same colors:

Sorry you have a 256 colors (or less) video system.

64 or 32K colors

These color tables have been developed around a theoretical gray (CIE-L*=85, a*=0, b*=0). This central gray has been selected in order to obtain RGB values close to the hexadecimal border point (CCh + ( (FFh - CCh) / 2 ) ) of a typical Web safe 216 colors palette.
The colors surrounding the gray central position have been calculated adding +5 or -5 to the standard's CIE-a* and CIE-b* values.
The colors directly in contact with the standard have a (CIE) Delta-E* of 5. The colors in the 4 corners have a Delta-E* of 7. All the colors differences are in hue and saturation as the CIE-L* value does not change.
All color data refers to the D65 illuminant and 2 (1931) observer.
