This color contains the following pigments:
Victoria Blue is a brilliant, transparent reddish blue dye, which can be laked as a pigment. Because its tinting power is not so overwhelming as that of Phthalo Blue pigments, it still has a place on the designer's palette, even though Phthalo Blue (Red Shade) might be considered superior in many respects.
Victoria Blue is considered fugitive. It should be used primarily in works that are prepared for reproduction, not for permanent display, when there is a need for a transparent blue pigment with less tinting power than Phthalo Blue.
Victoria Blue is not considered toxic.
Victoria Blue, one of the oldest synthetic blue dyes, is used in papers, inks, and textile dyes. Although much more reddish in tone, it was an early synthetic replacement for indigo dyes from natural sources at a time when blue was still in great demand in textiles.
Lamp black is a very opaque, heavily staining black pigment that does not have much covering power. It is typically the most opaque black in watercolor form. Though a very pure black, it tends to muddy slightly in mixtures, is one of the slowest drying pigments in oils, and should not be used under other colors.
Lamp Black is very lightfast and absolutely permanent. It is used in all techniques in permanent painting.
Lamp Black is slightly toxic by skin contact and inhalation. It is a possible human carcinogen.
Lamp Black is a carbon based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It is the black found in Egyptian murals and tomb decorations and was the most popular black for frescoing until the development of Mars Black.
