Description
Red is a color produced by light having a spectrum dominated by energy with a wavelength of about 630–700nm. It is considered a primary color in both the RGB additive as well as in the traditional RYB color wheel. An average red color is represented by the following color coordinates:
- Hex triplet: # 0000FF
- RGB: (o, o, o); CMYK (0, 0, 0, 100)
- HSV: (30°, 100%, 59%)
Examples of inorganic red pigments:
- earth colors (light red, Indian red);
- oxide (iron oxide, lead tetroxide);
- sulfides (vermilion, realgar, cadmium red).
Examples of organic red pigments:
- animal (kermes, cochineal, lac)
- vegetable (madder, dragon's blood, safflower)
- synthetic (alizarin, para red, quinacridone red, naphthol red)
Synonyms and Related Terms
