    Principle

    Coloring comparison usually occurs under sunlight in daily life, whereas industrial color comparison requires the light source with equivalent spectra distribution of sunlight, which is defined as D65 standard light source by International Commission of Illumination (CIE). However, metamerism effect always occurs when matching color. It makes the same specimen show different colors in different light source, which will lead to a great deal of loss. Application of "A" light source will effectively avoid such unfavorable effect.
