SPECTROPHOTOMETER CONFIGURATION FOR COA Type: Datacolor Illuminate: D65 Daylight Observer: 10 degree, large area view, specular included EXPLANATION OF SPECTROPHOTOMETRIC VALUES DL* Lightness/Darkness Difference (Delta L*) The shade of gray (black/white) + = Lighter - = Darker Da* Red/Green Color Difference (Delta a*) + = Hue is redder (or less green than) - = Hue is greener (or less red than) Db* Yellow/Blue Color Difference (Delta b*) + = Hue is yellower (or less blue than) - = Hue is bluer (or less yellow than) DC* Difference Attributed to Chromaticity (Delta C*) + = More saturated than (more color intensity) - = Less saturated than (less color intensity) DH* Difference Due to Hue Only (Delta H*) DE* Total Color Difference (Delta E*) DE is a mathematical calculation utilizing the DL*, Da* and Db*, and therefore, used alone this number can be misleading as to the true color of a material. We recommend that our customers visually determine if the color of the product is acceptable. USING THIS CHART This color selection chart is a tool to assist in selecting the proper colorants for specific applications. • C.I. numbers refer to the Color Index, the industry’s standard guide. • In each pair of color chips, the left sample represents the masstone or full shade, which is the color hue in clear media. • The chip on the right shows the relative tint strength using 10 parts TiO2.

Outdoor consumer applications where superior aesthetics, chemical resistance, UV stability, and high performance are critical, such as powersports, lawn and garden, and marine body panels and housings, are suitable candidates for customized Artisan formulations.
