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
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 ...

Haematoxylin or hematoxylin (/ ˌ h iː m ə ˈ t ɒ k s ɪ l ɪ n /), also called natural black 1 or C.I. 75290, is a compound extracted from heartwood of the logwood tree (Haematoxylum campechianum) [1] [2] with a chemical formula of C 16 H 14 O 6.
[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.
