Taking cues from hyper-pigmented reality, scientists are developing a coloration technique that produces vivid iridescent colors using wood pulp – the same stuff that is used to make paper. Researchers from Cambridge University manipulate the wood pulp to rearrange the cellulose within on the nanoscale to change their physical stacking, which in turn changes how they reflect light. The resulting, totally non-toxic film could be used to cover textiles, paper, and other materials that replaces the use of toxic dyes and creates color that would never fade.
