Yes I have painted 4 of them using a can gloss spray in bright yellow for the outer blades. On the inside of the blades I did one coat of a semi gloss interior house paint as a base coat. Then I used 8 vibrant colors of the rainbow of an Acrylic paint in 2 ounce bottles I bought at Hobby Lobby or Michael's. After painting the inside blades with the rainbow colors in order of the rainbow with 3 coats each blade. I finished with spraying them with a Krylon Crystal Clear Acrylic Coating to protect and seal the colors. When you see the sunflower spin it is very colorful to watch.
