The issue with the red version is odd, I've gone through quite a few variations, one where it was orange and yellow but I couldn't find a complimentary colour to go with it. I've made a more purpleish pinkish version and I'll show it off on TF2 Emporium and on my twitter to see what people think.

I dislike the red one, should be more like yellow/orange like sunset. Other than that it's great and would like to see it in game

I think changing the color to a more orange-ish one for RED would work well. Along with providing in-game screenshots to give people more information.
