I hope you like the stallion Peeta Lover c: I was super inspired by the music you listed if you couldn't tell x] he indeed has a white base color and black in his design.
In my mind his mane and tail doesn't actually flame like real fire. It's just colored like fire and he just happens to have a wavy hair texture. If you want him to have a real fire mane, well that's up to you. His cutie mark is the japanese sun design. I thought it was fitting. I can add a better reference for the red marking on his face if you want.
If you don't like him he'll be put up for adoption ^^ let me know what you think either way.
