Well I zoomed in closer to get a better look (only so I could properly answer your question of course) and I think I would say, both. She's a little orange and her suit is orange and the sand looks a little orangey. Reds are probably pumped up a bit across the whole image.
The question I'm really wondering about, however, is how her necklace appears to be defying gravity. Its hang looks as if she were standing straight up.
