Natural self-assembled photonic paintings- inspiration for a post-pointillist

Pachyrrhyncus gemmatus color colour

A beetle in colour under a low powered microscope. This may as well be a painting, a pointillist painting, or rather a 'post-pointillist' painting. To be post-pointillistic, I would recommend moving beyond the dyes and pigments of Seurat and Signac - on to a new use of light compared with conventional pointillism. A dot painting made of photonic crystals can make colour without normal dyes or pigments. A pointillist painting with no dyes or pigments? That equals post-pointillism to some extent surely? Christian Mille and I are studying these. Specimen NHM, Stockholm.
