Ok, so I'm editing a hand-drawn sketch for some cover art for my friend's band. I've got this great skyline with an eerie green glow to it, but when I save it there's no green in the sky. Right now, the sky's all one layer with a dark-green color overlay set to "color burn". It looks great in Photoshop but no matter how many different combinations of settings I try to save it with, the sky always comes out white in the final jpg/png. Does anybody know why this is?
