Green and purple are a good color match. Of course if you want to get into the full tertiary you could add some orange to round things out but I think this is looking pretty nice. Do you care? No? Either do I. Just eat it!
I'm beginning to think that there is no "too far" when it comes to worshipping Hello Kitty. You can find nearly any product, any food, any anything with her sweet little beady-eyed face on it. An incredible feat of branding!
