Color space The color-space concept was likely due to Hermann Grassmann, who developed it in two stages. First, he developed the idea of vector space, which allowed the algebraic representation of geometric concepts in formula_1-dimensional space. Fearnley-Sander (1979) describes Grassmann's foundation of linear algebra as follows: With this conceptual background, in 1853, Grassmann published a theory of how colors mix; it and its three color laws are still taught, as Grassmann's law. Colors can be created in printing with color spaces based on the CMYK color model, using the subtractive primary colors of pigment (cyan (C), magenta (M), yellow (Y), and black
Additive color Additive color Additive color is a method to create color by mixing a number of different light colors, with shades of red, green, and blue being the most common primary colors used in the additive color system. Additive color is in contrast to subtractive color, in which colors are created by subtracting (absorbing) parts of the spectrum of light present in ordinary white light, by means of colored pigments or dyes, such as those in paints, inks, and the three dye layers in typical color photographs on film. The combination of two of the standard three additive primary colors in
