Pearlescent of Interference series with colours such as platinum gold, red pearl, violet pearl, blue pearl, green pearl. With the same composition as KT 100 series, KT 200 bears thicker layer of titanium dioxide which caused lights interfere selectively. Viewing from certain angles, some colours are strengthened and the complementary ones are dimmed or disappeared. This results a dual-colour effect. Such an effect has to be treated carefully when applied with coloured base materials. The pearlescent colours can not be used with the complementary coloured base material, otherwise, the results can be dull or out of expectation. On the other hand, same colour phase can highlight the colour effect.
