Iron pigments

* Prussian blue (PB27): a synthetic inert pigment made of iron and cyanide: C18Fe7N18.

Manganese pigments

* YInMn Blue: a synthetic pigment discovered in 2009 (YIn1−xMnxO3).[3]
* Manganese blue: barium manganate(VI) sulfate.

## Green pigments

Cadmium pigments

* Cadmium green: a light green pigment consisting of a mixture of cadmium yellow (CdS) and chrome green (Cr2O3).

3,Si
4)O
10(OH)
2).

## Orange pigments

Bismuth pigments

* Bismuth vanadate orange (PO83) non-toxic pigment similar to vermilion.

Cadmium pigments

* Cadmium orange (PO20): an intermediate between cadmium red and cadmium yellow: cadmium sulfoselenide.

## Safety

A number of pigments, especially traditional ones, contain heavy metals such as lead, mercury, and cadmium that are highly toxic. The use of these pigments is now highly restricted in many countries.[1]
