What is hue?

sky is blue. "Hue" is the tint by which the color of an object is classified as red, yellow, blue, etc.
What is brightness?
"Brightness" is the degree of lightness in a color, as compared with another color, which makes it a light color
or a dark color. For example, when comparing the yellow of a lemon and the yellow of a grapefruit, it is
obvious that the yellow of the lemon is brighter. But what about when comparing the yellow of a lemon and
the red of a bean? Obviously, the yellow of the lemon is brighter. "Brightness" is this degree of lightness that
enables comparison regardless of the hue.
