Peerless Transparent Watercolors were developed in 1885 by Charles F. Nicholson. After many years of "revolutionary" chemical research, he developed the self blending line of Peerless Transparent Watercolors in sheet form. His unwavering ideal was to create an original form of presentation for watercolors. After many years of perseverance, he successfully developed Color Film, or paper leaflet paint as many used to call them. Watercolors had never been offered in dry form and the novelty of the idea seemed to shock the artistic sense of the professional colorist.The formula he created for his special watercolors in 1885 has never changed. After 122 years, the same process is used in the creation of the product. These liquid dyes are the very same watercolor dyes used to create the dry dye sheets.
Peerless retouching dyes do not fade and do not change color when heated.
Lamp Black is for retouching Black & White neutral tone prints.
Each color can be used individually or in combination with other colors for spotting any black & white print.
