Question

What is the difference between saturation and lightness?

Answer

Saturation refers to the intensity of a color or hue. 0% saturation will be a shade of gray whereas 100% saturation will be the purest form of the hue.

While saturation refers to the amount of grey in a color, lightness refers to the amount of white added to a hue. 0% lightness is black and 100 lightness is white.
