Hue, brightness and saturation are the elements that we call the “three attributes of color”. We can
think of their affects using the solid object shown in gure 1, where the outer edge is the hue, the
vertical axis is the brightness, and the horizontal axis from the center is the saturation.
Assigning colors to the solid object, representing the three attributes of color, shown in gure 1
produces the color model shown in gure 2. Although the level of saturation differs for each hue
and degree of brightness, creating a complex color model, we can get a better understanding of
the conditions under which the hue, brightness and saturation vary.
