Borbos's Joyous Wand of Color

This crystalline, prismatic wand can channel
the illustrative intent of its wielder. While holding the wand, you can cause the end to leave behind an arcane pigment of your choice, allowing you to draw in midair or on
any surface the end of the wand touches.
The effect is illusory, visibly magic, radiates
dim light out to 5 feet, and dissipates after
one hour of completing a drawing.
