At Material Evolution Lab we work with two main light-reactive pigments:
Photochromic
When exposed to UV rays, the bright colours of the photochromic pigment emerge from its previously unnoticeable white state.
Photoluminescent
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.
