That sounds like even more fun. Guess I'll have to learn how Hue, Saturation, and Brightness play a part together.
I am sure Brightness is just raising or lowering of all the values at the same time.
Hue from what I understand if the R G B value is 98 135 188 you would change 135 because it is the middle value (between 98 and 188) in order to keep Saturation and Brightness the same.
Saturation is the distance of 2 values in the spectrum. 98 135 188 you would change 98 and 188 respectively to change saturation because they are at the top and bottom of the spectrum for that color. The greater the distance the greater the saturation.
Please correct me if I am wrong.
