What is "hue"? how can hue affect artwork?

Changing the Hue of a picture sometimes results in a more flashy image, or intriguing shapes and colors. a white oval on a black background could become a flashy aqua and green shade with a almost white background. it all depends on the lighting and wavelengths.
