There's no right answer, it tells me that the Highlight is both purple and green at the same time? 
Thanks for checking it out! Looks like you're trying to test out all the color combinations . In that set of guesses, the highlight (the red splotch icon) is red both times, and you've tried purple and green for the top and bottom. Based on the clues, I bet that:
- The highlight (red splotch) must be purple or green.
- Either the top or the bottom (or both) must be red.
- The top and bottom shapes are not those two shapes.
