Darklight

You use your action to touch an object no longer than 10' in any dimension, causing it to shed dim light of a subdued color you choose in a 20' radius. This dim light overrides non-magical bright light and bright light created by cantrips. Bright light created by spells 1st level and higher overrides the dim light created by this spell. If the object is completely covered, the light is blocked. The spell ends if you cast it again or dismiss the darklight as an action.
