Paint

Paint is a copy ability introduced in Kirby Super Star back in 1996.

Kirby Super Star / Kirby Super Star Ultra
With the Paint copy ability, Kirby dishes out a paint bucket, hovers in the air splashing out colors of paint, defeating enemies on the screen. If this ability is used against Heavy Lobster, it causes it to be painted red, thus blinding it in the process. Paint also causes Chameleo Arm to change color (whether or not it's invisible).
