Cobalt pigments

Copper pigments

Iron pigments

Manganese pigments

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

Green pigments edit

Cadmium pigments

Chromium pigments

Cobalt pigments

  • Cobalt green: also known as Rinman's green or zinc green (CoZnO2).

Copper pigments

  • Malachite: cupric carbonate hydroxide (Cu2CO3(OH)2).
  • Scheele's Green (also called Schloss green): cupric arsenite (CuHAsO3).

Other pigments

  • Green earth: also known as terre verte and Verona green (K[(Al,Fe3+),(Fe2+,Mg](AlSi3,Si4)O10(OH)2).

Yellow pigments edit

Arsenic pigments

  • Orpiment: natural monoclinic arsenic sulfide (As2S3).

Bismuth pigments

Cadmium pigments

Chromium pigments

Cobalt pigments

  • Aureolin or cobalt yellow (PY40): potassium cobaltinitrite (K3Co(NO2)6).

Iron pigments

  • Yellow ochre (PY43): a naturally occurring clay of monohydrated ferric oxide (Fe2O3·H2O).

Lead pigments

Strontium pigments

Titanium pigments

Tin pigments

Zinc pigments

  • Zinc yellow (PY36): zinc chromate (ZnCrO4), a highly toxic substance with anti-corrosive properties which was historically most often used to paint over metals.

Orange pigments edit

Bismuth pigments

  • Bismuth vanadate orange (PO86): non-toxic pigment similar to vermilion.

Cadmium pigments

Chromium pigments

Red pigments edit

Arsenic pigments

  • Realgar: As4S4 - a highly toxic natural pigment.

Cadmium pigments

Cerium pigments

Iron oxide pigments

Lead pigments

Mercury pigments

Brown pigments edit

Clay earth pigments (naturally formed iron oxides)

  • Raw umber (PBr7): a natural clay pigment consisting of iron oxide, manganese oxide and aluminum oxide: Fe2O3 + MnO2 + nH2O + Si + Al2O3. When calcined (heated) it is referred to as burnt umber and has more intense colors.
  • Raw sienna (PBr7): a naturally occurring yellow-brown pigment from limonite clay. Used in art since prehistoric times.

Black pigments edit

Carbonaceous pigments

Iron pigments

Manganese pigments

Titanium pigments

White pigments edit

Antimony pigment

Barium pigments

Lead pigment

Titanium pigment

Zinc pigments

Fluorescent pigments edit

Safety edit

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]
