Pigment / Colour-Shift Lab Matter is a colour-shift pigment born in Semple's Lab. It reacts to sunlight, heat or darkness - shifting in colours in ways that are genuinely unpredictable. Each jar is randomly filled as experiments progress, so the exact colours and reactions are unknown until you open it. Mix it into SUPERBASE, resin, nail varnish, linseed oil, or any clear medium to make your own paint. "As the Lab works on experiments, these have been randomly jarred up - so what colours or reactions happen cannot be known beforehand." How to use it Mix the matter into SUPERBASE or any clear medium - resin, nail varnish, linseed oil. Use a small amount to start and build up. Works best in thin, translucent layers where the colour shift can breathe.
