Minerals

Minerals get their colour

• The presence of an element essential to the mineral composition

• The presence of a minor chemical impurity

• Physical defects in the crystal structure

• The mechanical mixture of very fine impurities

• The presence of finely-spaced structures in the mineral

How

For example Iwa-enogu is Japanese paint made from mainly minerals. The particles have a similar coarseness to sand and feature a lusterless matt feeling. The paint itself has no adhesive properties, but by adding glue, it sticks to the medium surface.

Mineral pigments are pigments that are created by combining and heating naturally occurring elements. They include ultramarine and spinel pigments.

Vegetable pigments

In fruits and vegetables almost all colors are caused by just 4 groups, or families, of pigments:

1. Chlorophyll (green) 2. Carotenoids (yellow, red, orange) 3. Flavonoids: anthocyanins + anthoxantins (red, blue, purple) 4. Betalains (red, yellow, purple)
