Colorants: color is the first thing that attracts the consumer to a textile. Color theory: complex phenomenon: physics of light, chemistry of colored objects, biology of the eye, behavioral sciences, and aesthetics. Metamerism: a color matches with one light source, but not with any other light source. Bezold effect: when two or more colors merge into one new color, i. e. , small scale print or yarn dyed fabric viewed from a distance. Color measurement: assign numerical values to a color, used to match color and sort shades. Color matching developing a formula to reproduce a color.
