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
Secondary color Secondary color A secondary color is a color made by mixing of two primary colors in a given color space. For the human eye, good primary colors of light are red, green, and blue. Combining lights of these colors produces a large range of visible colors. That is, the primary and secondary RGB colors (with secondary colors in boldface) are: Combining RGB colors means adding light (thus the term "additive color"), and the combinations are brighter. When all three primaries are combined in equal amounts, the result is white. The RGB secondary colors produced by the addition of light turn
