A demonstration of the production of the blue dye using sunlight to produce the blue colour is shown. The dye is extracted from the hypobranchial gland of H. trunculus snails. [43] Chemically, exposure to sunlight turns the red 6,6'-dibromoindigo in snails into a mixture of blue indigo dye and blue-purple 6-bromoindigo.
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. The molecule absorbs light in the orange part of the spectrum (λ max =613 ...
Bromophenol blue is also used as a dye. At neutral pH, the dye absorbs red light most strongly and transmits blue light. (Its peak absorbance is 590 nm at a basic pH of 12.) Solutions of the dye, therefore, are blue. At low pH, the dye absorbs ultraviolet and blue light most strongly and appears yellow in solution.
Other civilizations combined organic and mineral materials to create blue pigments ranging from azure-blue like the Maya blue [1] to the Han blue (BaCuSi 4 O 10), which was developed by the Chinese Han dynasty and manipulated to produce a light or dark blue color. [7] A number of pigments are used to impart the blue color.
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.
The color of a dye is dependent upon the ability of the substance to absorb light within the visible region of the electromagnetic spectrum (380–750 nm). An earlier theory known as Witt theory stated that a colored dye had two components, a chromophore which imparts color by absorbing light in the visible region (some examples are nitro , azo ...
Alternatively, fine-textured Egyptian blue consists of smaller clusters that are uniformly interspersed between the unreacted quartz grains and tends to be light blue in color. [13] Diluted light blue, though, is used to describe the color of fine-textured Egyptian blue that has a large amount of glass formed in its composition, which masks the ...
Hues of blue include indigo and ultramarine, closer to violet; pure blue, without any mixture of other colours; Azure, which is a lighter shade of blue, similar to the colour of the sky; Cyan, which is midway in the spectrum between blue and green, and the other blue-greens such as turquoise, teal, and aquamarine.
