Crimson is a strong, bright deep red color combined with some blue, resulting in a tiny degree of purple.

It is originally the color of the dye produced from the dried bodies of the cochineal insect (Coccus cacti); however the name is also used for slightly bluish red colors in general that are between red and rose.

[edit] Etymology

The word "crimson", recorded in English since 1416, in its earlier forms cremesin, crymysyn, also cramoysin, cf. cramoisy (a red cloth), is adapted via Old Spanish cremesin "of or belonging to the kermes", from the Medieval Latin cremesinus for kermesinus or carmesinus, the dye produced from the shield-louse Kermes vermilio (Coccus ilicis), Arabic & Persian قرمز qirmiz, which stems from Sanskrit krmi-ja (cognate with Latin vermis and English worm. From the Latin carminus, a shortened form of carmesinus, comes carmine), a compound meaning "(red dye) produced by a worm", from krmih "worm" + -ja, "produced" (from Proto-Indo-European *gene-). Cognates include O.C.S. čruminu, Russian čermnyj "red," from the same source. Cf. also vermilion.

[edit] Dyes

The insects were gathered commercially in Mediterranean countries, where they live on the Kermes oak, and sold throughout Europe. Kermes dyes have been found in burial wrappings in Anglo-Scandinavian York. It fell out of use with the introduction of cochineal. The dyes were comparable in quality and color intensity, but ten to twelve times as much kermes was needed to produce the same effect as cochineal.

Alizarin crimson is a pigment that was first synthesized in 1868 by the German chemists Carl Gräbe and Carl Liebermann and replaced the natural pigment madder lake. Alizarin crimson is a dye bonded onto alum which is then used as a pigment. It is not totally colorfast, when mixed with ochre, sienna and umber.

Main article: carmine

Crimson, or crimson Lake, or carmine is sometimes the names given to the dye made from the dried bodies of the female cochineals although it is more common to call the pigment "cochineal" after the insect from which it is made. It appears to have been discovered during the conquest of Mexico by Spaniard Hernán Cortés and brought to Europe in early 1500s. Carmine was first described by Mathioli in 1549.

Carmine is an aluminium and calcium salt of carminic acid and carmine lake is an aluminium or aluminum-tin lake of cochineal extract, whereas Crimson lake is prepared by striking down an infusion of cochineal with a 5 percent solution of alum and cream of tartar. Purple lake is prepared like carmine lake with the addition of lime to produce the deep purple tone. Carmine dyes tend to fade fast.

As a food additive, carmines have E number E120. It is also called cochineal and Natural Red 4.

[edit] Practical Uses

This dye was once widely prized in both the Americas and in Europe. It was used in paints by Michelangelo and on the fabrics of the Hussars, the Turks, the British Redcoats, and the Royal Canadian Mounted Police.

Nowadays carmine dyes are used for coloring foodstuffs, medicines and cosmetics. They are also used in some oil paints and watercolors used by artists.
