A Singer is wearing a blue outfit What color spotlights could be used to make the appear black?

Red, cyan, and green spotlights could be used to make the singer appear black. When these three colors of light are combined in equal amounts, they create the color black. This is because the human eye has three types of cone cells that are sensitive to different colors of light: red, green, and blue. When all three types of cone cells are stimulated equally, the brain interprets the color as black.
