The blackest of all blacks, it can unbalance the rest of the palette. It is best for special effects and has reddish undertones and tints.
The blackest of all blacks, intense carbon black is best for special effects. It has reddish undertones and tints and is rated as a slow drier. Like Ivory black, the name refers to the history of the pigment—the burning or carbonizing of natural gas, oil, wood, vegetables, and other organic matter. This super-dark black absorbs enormous amounts of light, making it the most robust black.

Properties
Lampblack is an opaque, heavily staining black pigment with little covering or tinting power. It is typically the opaquest black in watercolour form. Though a very pure black, it tends to muddy slightly in mixtures. Natural sources may be brownish or bluish in tone because of impurities. When used in oil paints, it is one of the slowest drying pigments and should not be used in underpainting or applied in layers underneath other colours.
Permanence
Lamp Black is very lightfast and permanent. It is used in all techniques in permanent painting.
Toxicity
Carbon itself is not considered hazardous; however, other dangerous combustion products are often present as impurities when Lamp Black is produced from natural materials. For this reason, commercial preparations of the pigment should be considered.
History
Lamp Black is a carbon-based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It has been used as a pigment since prehistoric times. It is the black found in Egyptian murals and tomb decorations and was the most popular black for fresco painting until the development of Mars Black.
