The plastic library consists of 197 colors that are excellent visual matches to existing ColorWall colors under multiple light sources (D65, F02, A10, & UL3000). In addition to the ColorWall shades, 16 very popular fluorescent colors are also part of the set. The 2” x 3” polypropylene-based plastic chips were selected from a wide range of relevant “real-world” colors that display an excellent coverage of color space.
