Color model meaning in Digital terms is A color model is a way of specifying or describing a color numerically; common examples include RGB, HSV and CMYK. For example, in the 24-bit-deep RGB color model, the intensity of each of the red, green and blue components of the model (8 bits for each channel) are represented on a scale from 0 to 255. The lowest intensity of any color represented by 0 and 255 representing the maximum intensity.There are two main categories of color models, additive and subtractive. Additive color models (such as RGB) are based on transmitted light while subtractive color models (such as CMYK) are based on reflected light.
