The pigment is the highest volume pigment produced. [19] All major artists' pigment manufacturers produce variants of copper phthalocyanine, designated color index PB15 (blue) [20] and color indexes PG7 and PG36 (green). [21] A common component on the artist's palette, phthalo blue is a cool blue with a bias towards green.
In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is.
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
Colour Index International resolves all these conflicting historic, generic, and proprietary names so that manufacturers and consumers can identify the pigment (or dye) used in a particular color product. In the CII, all phthalocyanine blue pigments are designated by a generic color index number as either PB15 or PB16, short for pigment blue 15 ...

It is a representative of "complex inorganic colored pigments," or CICPs. More specifically, bismuth vanadate is a mixed-metal oxide. Bismuth vanadate is also known under the Colour Index International as C.I. Pigment Yellow 184. [2] It occurs naturally as the rare minerals pucherite, clinobisvanite, and dreyerite.
