Cottonmix is a cotton-based plaster used for (acoustic) finishing for walls and ceilings.
Paint containing vegetable colorant from Rubia has been incorporated into a Rigo natural paint base. Cottonmix can be produced in various textures. Spraying a wall with it from various angles creates a unique colour depth.
The wall will appear almost luminous from certain angles, while from others the rough texture might create countless shadows.
