8. Color Space A color space is a model for representing set of colors numerically or mathematically in terms of three or more coordinates. A color space is a model for representing set of colors numerically or mathematically in terms of three or more coordinates. Color space can be mapped into a 2-D, 3-D, or 4-D coordinate system similar to a Cartesian coordinate system.
