What is saturation?
What makes the difference between the yellow of a lemon and the yellow of a pear? By saying that the lemon
is a more vivid yellow and the pear is a duller yellow, the difference between the two colors is stated in terms
of "saturation", as opposed to "brightness". As opposed to hue and brightness, "saturation" is the
characteristic that indicates the degree of vividness.
