Solution
change its color. This is due to the phenomenon of light interference. When light hits the thickened oxide layer, some of it reflects off the surface of the oxide, and some of it penetrates the oxide and reflects off the underlying metal. These two reflected light waves interfere with each other, either strengthening or canceling each other out, which results in different colors being visible. The specific color seen depends on the thickness of the oxide layer, which can be precisely controlled by the artist using heat or electricity. This allows the artist to create a wide range of colors on the titanium surface, making it a versatile medium for their artwork.
