Editing RGB color model (section)

===Color depth===
{{main|Color depth}}

The RGB color model is one of the most common ways to encode color in computing, and several different [[Digital signal (signal processing)|digital representations]] are in use. The main characteristic of all of them is the [[Quantization (signal processing)|quantization]] of the possible values per component (technically a ''[[sampling (signal processing)|sample]]'') by using only [[integer]] numbers within some range, usually from 0 to some power of two minus one (2<sup>''n''</sup>&nbsp;−&nbsp;1) to fit them into some bit groupings. Encodings of 1, 2, 4, 5, 8, and 16&nbsp;bits per color are commonly found; the total number of bits used for an RGB color is typically called the [[color depth]].
