EXPANSION OF COLOR SPACE in Architectural Coatings

摘要

Point-of-sale (POS) paint tinting has been prevalent in the North American market for the last 50 years. The first POS system introduced by a Colortrend USA LLC predeces-sor company had a line-up of 12 colorants.These standard 12 colorants laid the cornerstone for the machine tinting and color system concept used globally. It is not uncommon for other color systems to have 9 or even 10 colorants, and in Europe, there are some systems containing as many as 16 colorants. Even though there is a wide variety in the number of colorants used, the ultimate color space or gamut is determined by the chroma (or brightness) of the organic colorants in the lineup. This color space incorporates colorants such as organic yellow, medium yellow, organic red, magenta, phthalo blue and phthalo green, with the lightness/darkness determined by the black and white.
