Colour without pigment
In development
A butterfly wing is blue with no blue in it. Surfaces that make colour from structure alone.
A butterfly wing produces its colour through structures a few hundred nanometres across that interfere with light. There is no pigment and no dye.
MABE designs surface structures that produce specific colours from optical physics alone: colour that does not fade, because there is nothing in it to break down, and that needs no dye bath to apply.
