Persian blue: made by grinding up the mineral Lapis lazuli. The most important mineral component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral with the formula (Na,Ca) 8 (AlSiO 4) 6 (S,SO 4,Cl) 1–2. Cobalt pigments. Cobalt blue (PB28): cobalt(II) aluminate. Cerulean blue (PB35): cobalt(II) stannate. Cerium uranium ...
Brazilin is a naturally occurring, homoisoflavonoid, red dye obtained from the wood of Paubrasilia echinata, Biancaea sappan, Caesalpinia violacea, and Haematoxylum brasiletto (also known as Natural Red 24 and CI 75280). [1] Brazilin has been used since at least the Middle Ages to dye fabric, and
A dyewood is any of a number of varieties of wood which provide dyes for textiles and other purposes. Among the more important are: Brazilwood or Brazil from Brazil, producing a red dye. Catechu or cutch from Acacia wood, producing a dark brown dye. [1] Old Fustic from India and Africa, producing a yellow dye. [2] Logwood from Belize, producing ...
If the dye has the opposite charge, it is attracted to and retained by this coating, while the solvent soaks into the paper. Cellulose, the wood-derived material most paper is made of, is naturally charged, and so a compound that complexes with both the dye and the paper's surface aids retention at the surface. Such a compound is commonly used ...

[5] Synthetic dyes are produced from various chemicals. The great majority of dyes are obtained in this way because of their superior cost, optical properties (color), and resilience (fastness, mordancy). [2] Both dyes and pigments are colored, because they absorb only some wavelengths of visible light. Dyes are usually soluble in some solvent ...
[16] [27] Other components of colorant molecules can tune intensity, color, solubility and substrate affinity. Dyes and pigments can be categorized according to their synthetic or chemical properties. British chemist Edward Chambers Nicholson showed that pure aniline produced no dye. Hofmann showed that toluidine must be present to make these dyes.
