incredibly blind fandom moments

In the category of yes, I am a blind fan, and I'm being literal with that descriptor. Can somebody clue me in as to what two particular ML characters look like? I'd click on the fandom wiki page for one of them, but that page carries a gigantic flippin' spoiler warning at the top, and I do N-O-T want to step into a nest of spoilers! Definitely not before I finish this AU, because I've got a particular power set and mode, as well as personalities in mind, and I have little doubt it'll all get thoroughly jossed either if I'm spoiled or when I catch up on canon. Both, really. So!

I know Duusu is blue and feathery, with a masculine peafowl tail. That's about all I know! Someone said pink eyes, as in pink irises, in a fic the other day; is that true? Basically, what's that kwami look like?

Also, Émilie is a blonde, I believe? Is it visible in canon if she's taller, shorter, slim like Adrian, anything? I've been picturing her as thinner but not at all unhealthy, and golden blonde rather than silvery or straw.

And, while I think of it, is Gabriel also fair in coloration? Does Adrian get his green eyes from him, or from his mother, or potentially from both of them? Or do we know?

Asking in the name of not frakking up details in fiction, wheeeee!
