The pigment is noteworthy for its vibrant, near-perfect blue color and unusually high NIR reflectance. [1] [2] The color may be adjusted by varying the In/Mn ratio in the pigment's base formula of YIn 1−x Mn x O 3, but the bluest pigment, YIn 0.8 Mn 0.2 O 3, has a color comparable to standard cobalt blue CoAl 2 O 4 pigments.

Silicate mineral paints or mineral colors are paint coats with mineral binding agents. Two relevant mineral binders play a role in the field of colors: Lime and silicate. Under influence of carbon dioxide, lime-based binders carbonate and water silicate-based binders solidify. Together they form calcium silicate hydrates. [1]
A range of other minerals may also be included in the mixture: [6]: 134 Yellow ochre (Goldochre) pigment. Yellow ochre, FeO(OH)·nH 2 O, is a hydrated iron hydroxide (limonite) also called gold ochre. Red ochre, Fe 2 O 3 ·nH 2 O, takes its reddish colour from the mineral hematite, which is an iron oxide, reddish brown when hydrated. [7]
Ochre, iron oxide, was the first color of paint. [7] A favored blue pigment was derived from lapis lazuli. Pigments based on minerals and clays often bear the name of the city or region where they were originally mined. Raw sienna and burnt sienna came from Siena, Italy, while raw umber and burnt umber came from Umbria. These pigments were ...
Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder.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.
