Color gamut of cholesteric liquid-crystal films and flakes by standard colorimetry

Abstract

Despite angle dependence and polarization selectivity, the color of cholesteric liquid-crystal (CLC) polysiloxane films can be quantified by standard colorimetry. A new fractured form of the film called “flakes” makes it possible to use the Center of Gravity Color Mixing Principle to predict the chromaticity of CLC color mixtures. A complete color gamut can be produced by layering CLC films, mixing CLCs physico-chemically, and mixing CLC flakes. © 1998 John Wiley & Sons, Inc. Col Res Appl, 23, 210–220, 1998
