“Color Image Adjust” Function
Relationship between hue, brightness and saturation (color model)
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 figure 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 figure 1 produces the color model shown in figure 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.
