RGBA stands for red green blue alpha. While it is sometimes described as a color space , it is actually a three-channel RGB color model supplemented with a fourth alpha channel . Alpha indicates how opaque each pixel is and allows an image to be combined over others using alpha compositing , with transparent areas and anti-aliasing of the edges ...
These palettes only have some shades of gray, from black to white (considered the darkest and lightest "grays", respectively). The general rule is that those palettes have 2 n different shades of gray, where n is the number of bits needed to represent a single pixel.

A hex triplet is a six-digit (or eight-digit), three-byte (or four-byte) hexadecimal number used in HTML, CSS, SVG, and other computing applications to represent colors.The bytes represent the red, green, and blue components of the color.
Then change the color with the cursor or enter the RGBA code of a color. (A=alpha, normally 255=opaque). Note: you can select several zones at the same time, and change their color at the same time, by clicking whilst pressing the shift key.
This article is a list of the color palettes for notable computer graphics, terminals and video game console hardware.. Only a sample and the palette's name are given here. More specific articles are linked from the name of each palette, for the test charts, samples, simulated images, and further technical details (including referenc
