Hello!
I'm new to the processing community and new to programming (total noob) in general. In this sketch I am trying to make a super basic color picker/drawing program. My main problem is that I cannot figure out how to make a default color that can then be altered. For instance, when my sketch is started, you have to choose from the two color bars in order to get a color that is then used for the drawing. I would like to make it so when you open the sketch it starts with a color and then I can select from the bars when I want to change the color. I'm sure this isn't very efficient code, but I'm not really worried about that right now. Thanks in advance for any help!
