Senshoku

Senshoku (Japanese: 染色せんしょく Romaji: senshoku, tranlated as Dyeing) is a spell thought to belong to earth shamanistic magic. This is merely the spell's function, not its name, as the Power Words are unknown.

It enables the caster to change the color of his surroundings. It only affects the materials' surface, but the spell can be used to achieve complex visuals.
