Oklab's model is fitted with improved color appearance data: CAM16 data for lightness and chroma, and IPT data for hue. The new fit addresses issues such as unexpected hue and lightness changes in blue colors present in the CIELAB color space, simplifying the creation of color schemes and smoother color gradients.

Level 4 of the CSS Color specification introduced several new CSS color formats. [ 24 ] Besides new ways to write colors, it also introduces the concept of mixing colors in a non- sRGB color space, a first step towards fixing a well-known issue in color gradients .
The typical range of intensity values for each color, 0–255, is based on taking a binary number with 32 bits and breaking it up into four bytes of 8 bits each. 8 bits can hold a value from 0 to 255. The fourth byte is used to specify the "alpha", or the opacity, of the color. Opacity comes into play when layers with different colors are stacked.
Instead use non-colour techniques such as labelling, font styles (bold or italic), line styles (dots and dashes) or cross-hatching (stripes, checkers or polka-dots). If you are colour-blind yourself, check your revised image with a colour-sighted person to confirm the meaning is intact.
In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It was traditionally shipped with every X11 installation, hence the name, and is usually located in <X11root> /lib/X11/rgb.txt .
In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.
Xona.com Color List--This site has color coordinates, but it is not an authoritative source--most of the color names are purely arbitrary inventions like the names in a paint store catalog (in fact a large percentage of the color names are from the RGB Values list of Resene Paint Ltd.); this site should only be used for colors that are not on ...
A superset of CSS 1, CSS 2 includes a number of new capabilities like absolute, relative, and fixed positioning of elements and z-index, the concept of media types, support for aural style sheets (which were later replaced by the CSS 3 speech modules) [47] and bidirectional text, and new font properties such as shadows.
