I think it describes a relationship I have. For me, "you only loved in red" describes lust. I loved this guy for all the things he was, in so many various ways. But he only lusted over me, of course since HE only saw in black and white it was all he knew about love. So, I loved in colors he could never see, and he never felt. And we came from two completely different worlds. And I still love him, as a brother and a friend. And know that he's not the one. That's how I relate to the song anyway.

I like the line, "and I loved you unprotected, but you only loved in red".
