Fair enough. I've confused myself as well.
Here's the image in a rough form.
I don't want the girl to be coloured orange, she's supposed to be coloured greyscale essentially. The only way I can get her to be grey is if I put her in front of the first line of fire, which makes it look awkward. However when I clip the initial layer this happens.
I just tried restarting it with black, a beige, a red and a blue, and none of them even came close to resembling fire the way white does. Hopefully that partially helps out wiht your confusion about my confusion...
