At Material Evolution Lab we work with two main light-reactive pigments:
When exposed to UV rays, the bright colours of the photochromic pigment emerge from its previously unnoticeable white state.
Photoluminescent pigment lays dormant, absorbing light energy to then re-emit this energy luminous colour in the dark. These pigments also fluoresce when exposed to a strong UV light source.
