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)
