Clay nanosheets produce bright structural colours

Structural colours
Creating colour: nanothin clay double layers (DBLs) can generate structural colours. The colour is determined by the distance between the layers, which is modified by altering the clay concentration (shown far right) or the amount of salt in the material that the clay is suspended in.

Researchers in Norway and Germany have shown that structural colouration can be easily created from
