Colorblind

You target one creature that you can see within range and attempt to blind them with a dazzling display of lights that only they can see. The target must make a Constitution saving throw. On a failure, the creature is blinded until the end of your next turn. If the creature has Light Sensitivity or Sunlight Sensitivity, they make their saving throw with disadvantage. A creature is immune to this spell’s effects if they rely on another way to see without using their eyes, such as with blindsight or tremorsense, or they see through illusions, as with truesight.
