9:17AM - 'Twilight' question

I keep starting and dropping the books in a struggle between my curiosity boosted by all the posts in f_w and (lack of) tolerance for books focusing on high school romance, and a description of vampires I came across a few times sounds like a strange joke, so I thought I'd check its veracity here.

The vampires' eyes are a deep crimson when they feed on humans, but golden if their diet is animal-based. Now, maybe cannibalism of sorts does make differently sourced blood do different things, but I keep having visits from Logic with the following riddle:

red eyes : consumed blood = golden eyes : ???

D:

Please, writers, think things through!
