Does anyone have any good tutorials on freehanding scales? The person playing this character requested "Purple but the top is green". That was vague as shit, but I'm guessing they mean a purple to green transition with scales since it's a dragon, but the model doesn't have scales, so I'll need to freehand it. I'm thinking of maybe using this method to at least draw in the scales with bright green skin underneath and dark purple scales on top or the other way around. Also I don't know how I'm supposed to transition between opposite colours anyway.
