What is the exact relation or difference between a color model and a color space? I find these two terms to be used interchangeably in some literature. Are they simply the same?
Thanks!
Answer
A color model is a method of describing a color. For example with Red, Green and Blue (RGB) elements or with Cyan, Magenta, Yellow and Black (CMYK).
A color space is the set of colors which can be displayed or reproduced in a medium (whether stored, printed or displayed). For example, sRGB is a particular set of intensities for red, green and blue and defines the colors that can be reproduced by mixing those ranges of red, green and blue.
