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

rød (Dan.); Rot (Deut.); rojo (Esp.); pigments rouges (Fr.); rosso (It.); ruber (Lat.); rood (Ned.); röd (Sven.); pigmentos vermelhos (Port.)
