Hi

I have a newbie question

Goal, I have a control window in controlP5
I would like to make a color picker in this window that works in HSB not RGB

I will make 3 filled areas, Hue, Saturation and Brightness, the S and B would update to the current Hue and S or B respectively. These would be drawn with lines that vary in color along x

Question 1:
Problem, I have tried to set the color mode in the control window to HSB but I am doing it wrong or something, I probably don't know how to do it for the 'extra' window

Question 2: If I can't set the color mode in the control window, I could create the colors in HSB and convert to RGB to draw the lines. I have found in this forum the best way to do that is to use the java class color.
How do I add this library to my sketch?

Thanks!
