Selecting the correct colors for you painting is easy for some but not for others. Steph Sweeting recommended a wonderful video by Unmask Art on Youtube that showed how to use a free website PIXLR.com to select a color palette. I created my own video on just this portion with an example from the upcoming Green Iguana painting class (June).
I hope this is helpful. The Unmask Art video is referenced in my video. Enjoy and try it!
