Safflower petals contain one red and two yellow dyes. In coloring textiles, dried safflower flowers are used as a natural dye source for the orange-red pigment carthamin. Carthamin is also known, in the dye industry, as Carthamus Red or Natural Red 26. [26] Yellow dye from safflower is known as Carthamus yellow or Natural Yellow 5. [27]
Carthamin is a natural red pigment derived from safflower (Carthamus tinctorius), earlier known as carthamine. [2] It is used as a dye and a food coloring. As a food additive, it is known as Natural Red 26. Safflower has been cultivated since ancient times, and carthamin was used as a dye in ancient Egypt. [2]
In Japan, dyers have mastered the technique of producing a bright red to orange-red dye (known as carthamin) from the dried florets of safflower (Carthamus tinctorius). A bath solution of cold water is first prepared, to which is added the collected flowers.
Safflower (Carthamus tinctorius) is a flowering plant native to Asia that produces a substantive yellow dye for natural fibers. Dried safflower blossoms can be used to produce yellow, mustard, khaki, olive green and red colors.

Tartrazine was discovered in 1884 by Swiss chemist Johann Heinrich Ziegler, who developed the yellow azo dye in the laboratories of the Bindschedler'sche Fabrik für chemische Industrie in Basel . This was patented and produced in Germany by BASF in 1885 (DRP 34294).
The coloring is usually either the petals of safflower, or a solution of carmine in ammonium hydroxide and rosewater perfumed with rose oil. A cream-based variant of rouge is schnouda, a colorless mixture of Alloxan with cold cream , which also colors the skin red [ citation needed ] .
