The number of colors that can be represented by this system is 256 3, 16 6, or 2 24 = 16,777,216. ... CSS also supports the special color transparent, ...
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.
In these cases, the transparent palette entry number is defined by the hardware, and it used to be the number 0. Some indexed color image file formats as GIF natively support the designation of a given palette entry as transparent, freely selectable among any of the palette entries used for a given image.
If working with transparency, check the rules in use for your situation. The color at a point, where color G1 and G2 are to be combined, is ( G1 + G2 ) / 2. Some consequences of this are: Where the colors are equal, the result is the same color because ( G1 + G1 ) /2 = G1. Where one color (G1) is white (0.0), the result is G2 / 2. This will ...
The other video modes are similar to the GBA, but feature some enhancements. For example, the DS provides a number of 16 extended 256 color palettes for backgrounds as well as sprites on each of the two screens, allowing for a total of 8192 colors per frame (the practical number may be less due to some of the colors being considered transparent).
The Printer Working Group (PWG) of the IEEE publishes a standard, PWG 5101.1, whose mandatory color names are based upon RFC 3805, successor to RFC 1759 which imported the functional color names other, unknown and transparent alongside seven basic colors from ISO 10175 and ISO 10180 , and JTAPI.

Initially, the limited color depth of most video hardware led to a limited color palette of 216 RGB colors, defined by the Netscape Color Cube. The web-safe color palette consists of the 216 (6 3 ) combinations of red, green, and blue where each color can take one of six values (in hexadecimal ): #00, #33, #66, #99, #CC or #FF (based on the 0 ...
