Why do insect see white flour as purple color?

Insects perceive colors differently than humans due to variations in their visual systems. Many insects have photoreceptors that are sensitive to ultraviolet light, which is invisible to humans. When light reflects off white flour, it may emit UV wavelengths that insects can detect, causing them to see the flour as purple or another color that includes UV components. This ability helps insects navigate their environment and locate food sources more effectively.
