They light up my garden - 1 point 5. Painted could be a plus. The alternative appears to be colored plastic. There is nothing less natural than plastic. Plastic often fades.
Plastic can get real ugly.
Especially if it s a plastic flower. However, paint can be a minus if it s too bright, badly done, or not well kept-up. And most painted ornaments are not in natural colors and so leap out at the unwary visitor before they can actually see and notice the growing things. It s soooo subtle. . . This is an unscored question.
