Indigo, space-filling. Indigo dye is a dark blue crystalline powder that sublimes at 390–392 °C (734–738 °F). It is insoluble in water, alcohol, or ether, but soluble in DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid. The chemical formula of indigo is C 16 H 10 N 2 O 2 .
Tyrian purple is a pigment made from the mucus of several species of Murex snail. Production of Tyrian purple for use as a fabric dye began as early as 1200 BC by the Phoenicians, and was continued by the Greeks and Romans until 1453 AD, with the fall of Constantinople.
Deep blue. B: Normalized to [0–255] (byte) Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder. [2] Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold.
Brilliant blue FCF ( Blue 1) is a synthetic organic compound used primarily as a blue colorant for processed foods, medications, dietary supplements, and cosmetics. [ 1] It is classified as a triarylmethane dye and is known under various names, such as FD&C Blue No. 1 or acid blue 9. It is denoted by E number E133 and has a color index of 42090 ...
Kyanite is an aluminum silicate mineral, with the chemical formula Al2SiO5. It is typically patchy blue in color, though it can range from pale to deep blue [6] and can also be gray or white or, infrequently, light green. [7] It typically forms sprays of bladed crystals, but is less commonly found as distinct euhedral (well-shaped) crystals ...
The suffix "R" in the name of Coomassie brilliant blue R-250 is an abbreviation for "red" as the blue colour of the dye has a slight reddish tint. For the "G" variant the blue colour has a more greenish tint. The "250" originally denoted the purity of the dye. The colour of the two dyes depends on the acidity of the solution.
Chemical structure of C.I. Acid Blue 9, a dye commonly used in candies. Blue dyes are organic compounds, both synthetic and natural. [30] Woad and true indigo were once used but since the early 1900s, all indigo is synthetic. Produced on an industrial scale, indigo is the blue of blue jeans. For food, the triarylmethane dye Brilliant blue FCF ...
