Vantablack grown on metal foil. CVD Vantablack is composed of a forest of vertical carbon nanotubes "grown" on a substrate using a modified chemical vapor deposition process. When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. [24]
Cobalt pigments. Aureolin or cobalt yellow (PY40): potassium cobaltinitrite (K 3 Co(NO 2) 6). Iron pigments. Yellow ochre (PY43): a naturally occurring clay of monohydrated ferric oxide (Fe 2 O 3 ·H 2 O). Lead pigments. Naples yellow (PY41). Lead-tin-yellow: PbSnO 4 or Pb(Sn,Si)O 3. Titanium pigments. Titanium yellow (PY53): NiO·Sb 2 O 3 ...
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.
Super black is a surface treatment developed at the National Physical Laboratory (NPL) in the United Kingdom. It absorbs approximately 99.6% of visible light at normal incidence, while conventional black paint absorbs about 97.5%. At other angles of incidence, super black is even more effective: at an angle of 45°, it absorbs 99.9% of light.

Several commercial optical black coating products such as Vantablack and adVANTA nanotube optical blacks [23] have been produced from VANTA coatings. VANTA absorbers may also increase the absorption of heat in materials used in concentrated solar power technology, as well as military applications such as thermal camouflage.
This ink is made with soot from burning particular woods, bound with animal glue, and the method of application results in a greenish black color in the skin. [37] In the Māori tattoo practice, tā moko, tattoo experts have made ink from the ashes of resinous tree parts (such as kauri gum) or caterpillar fungus, mixed with oil from plants. [38 ...
