In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). [1] [2] A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.
Systems with a 12-bit RGB palette use 4 bits for each of the red, green, and blue color components. This results in a (2 4) 3 = 16 3 = 4096-color palette. 12-bit color can be represented with three hexadecimal digits, also known as shorthand hexadecimal form, which is commonly used in web design. The palette is as follows:
Typically they take a web page or image file as an input, and render a colour-blind simulated image as output: Mozilla Firefox color-blind addons; Sim Daltonism simulates color blind vision and displays the results in a floating palette for macOS and iOS.

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.
The edges of characters and other images with transparent background should not have shades of gray: these are normally used for intermediate colors between the color of the letter/image and that of the background, typically shades of gray being intermediate between a black letter and a white background. However, with, for example, a red ...

* Prior to standardization as a web color, Gainsboro was included as one of the X11 color names. [14] It was, however, absent from the original 1987 version of the list, [ 15 ] but present in Paul Raveling's version [ 16 ] which added, amongst other things, "[l]ight and off-white colors, copied from several Sinclair Paints color samples".
