Origami puzzles are usually paper variations of wooden puzzles. While trying to create new origami puzzles I realized I can exploit the color change feature of Kami. This simple heart shaped unit does just that.
Your challenge is to create a white square with 4 heart units without overlap! Units can touch each other only at the edges. It does not matter what happens to the rest of the unit as long as you get a white square. Happy Puzzling!

For the advanced solver, can you do it with only two units following the same rules?
