Explanation:

Zinc oxide is a white powder, when heated strongly (above 8000C) it turns yellow, but again becomes white again when cold. The hot zinc oxide absorbs some of the blue wavelengths of light making the reflected light more yellow. The loss of oxygen makes it a reversible chemical change.
