The reason it is 255 is because, typically, a color is stored in three bytes, or 24 bits, of data. This is convenient, is generally “good enough”, and doesn’t waste much data. Since each of red, green and blue get eight bits of data, that means there are 256 possible values. 0 is the lowest, 255 is the highest.

Why is there only RGB?
