From the moment an artist completes an oil painting, the painting begins to change color. The shift is gradual, taking decades, or even centuries, but eventually colors fade, darken, or become more transparent over time. ... Environmental contaminants can also be damaging to colors.

If this helps then plzzzzz mark me brainliest.
