Charizard has been shown with normal and blue fire but what about green, purple, or even pink? If you had fire type Pokémon, what is your preference of fire color? Personally I do love blue fire the most.
I like blue fire, but I feel like it's a bit overused. I'd like to see other kinds of flame be used more. Green flame would be interesting, but I really want to see purple for some reason. Another idea I had was Nega-Flame - a fire that burns black and sucks the light away instead of producing it.
