When I try to add white highlight to a colored object, as instructed in the tutorials, I 'lock transparency'. Well, that part works, but whatever color I try to paint over the colored object will not come out the color it's meant to be. If I 'unlock transparency', I can get the correct color, but then I'm not getting the feature of being able to stay within the lines only. I can't for the life of me see what I'm doing differently from the instructor. Thanks
