color shifting pigment for resin

KT-97543 is a Blue/Violet chameleon mica powder built for resin work — a multi-layer interference pigment on a natural mica substrate that shifts color with viewing angle, from blue at normal incidence to violet at a glancing angle. In our lab, the effect reads strongest over a black or very dark base layer, so we usually pair it with a black resin backing coat. Typical loading runs 1–10% by weight.
