The system is based on three basic colours, red, green and blue, and thus creates 12 main colours, arranging them in a pleasing colour-solid of varying triangles which allows for differences in intensity and saturation. This may be an appropriate point to review the experimental evidence for Hering’s four-colour theory, just as we have done with the Young-Helmholtz trichromatic theory and the «on-centre» and «off-centre» nerve-cells.
