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
Blue–green distinction in language "siwy" means blue-gray in Polish (literally it means the color of gray hair). The word "siny" refers to violet-blue and is used to describe the color of bruises ("siniaki"), hematoma, and the blue skin discoloration that can result from moderate hypothermia. Russian does not have a single word referring to the whole range of colors denoted by the English term "blue". Instead, it traditionally treats light blue (голубой, "goluboy") as a separate color independent from plain or dark blue (синий, "siniy"), with all seven "basic" colors of the spectrum (red–orange–yellow–green–голубой / "goluboy" (sky blue, light azure, but "does not equal"
