Color

"I'm the 'Purple Wizard'! I need a purple horse!"

"Well, invent a colorizing spell or summat, right?"

This spell transforms the exterior color of a target you touch into one of your choosing. The target area covers up to one large creature or object. If the object or creature is too large, the magic is diffused and the effect fades instantly. An unwilling creature must make a Constitution saving throw to avoid the effect. A shapechanger may end the effect when it changes shape. 

The transformation lasts for the duration, until dispelled, or until the target drops to 0 hit points, dies or is destroyed.

The new color can be any single color or shade you choose. Black, white and grey count as colors for the spell's purposes. The target's game statistics, including mental ability scores (if any), are unchanged. On living creatures, eye colors do not change. 

Spell components disappear when the spell is cast.
