$1+ I need help deciding on merch! (Patreon)

I was thinking about what color the hearts should be on the bright red leggings, and I thought black might look nice, but now that I have a mock up, I am not so sure. 

What do you think? If not black, what color should the hearts be? A mint green? The regular red so that they blend in a bit? Please post in the comments what colors you think would work (if not black) and maybe I will make a second poll with your recommendations!

Here are the other colors so far:

Thanks for the design help, guys!
