The weird damn things about wings was they almost always didn't match their owners.

For example, Cas' wings were kinda dark brownish black. He's one of the most naive dudes I've ever met (Yes, Sam, I know he doesn't have a gender but he's using a dude's body so he's a dude. It would be weird, like calling Baby 'Dude'. In what freakin' universe would anyone ever call my Baby a guy? What do you mean that's different, that's totally legitimate. )

Basically, he's really, like…innocent. In a lot of ways. It doesn't really match.
(Yeah, Cas, I know you're an angel warrior of the Lord, got it, thanks, memo received.)
(Sam, I know he's super strong but I'm talking, like, figuratively. Bitch, why're you laughing?)

Fine, whatever, new example.
Lucifer's wings are white. (Hey, you can shove it, Sam, you're the pissy princess who didn't agree with the first example, so suck it.)

Not like, snow white, like legit Downey Ultra Soft Get Some Sunglasses This Bastard's Got Glare In My Eyes White.

Seriously. The Devil has white wings.
Satan, the all evil and stuff.
(What do you mean technically all evil is the AntiChrist, Cas, the kid was way more likable than Lucifer, seriously. Yes I know you got turned into a plastic figurine, but it was more like time out. And you did try to kill him.)

(Sam, what the hell, what's he doing? What is that?)

(What do you mean he's ignoring me?!)

Well. Anyways, you'd think Hell disagreed with super white wings-
(What was that Cas?)

(No, Sam isn't your PA system, you got something to say, you can say it to me.)

(Morningstar? Cas, what the fuck does that even mean? ...So? He's Satan for crying out loud. What's wrong with you people?! Cas if you say you're not people I will bitch slap you so hard. No. Don't even. Just. Just don't.)

You know what, FINE.

Gabriel's wings are gold. TELL ME PLEASE, that that is not weird at all.
Seriously.

Go on. SOMEONE tell me that's not way off, please. Oh, no takers?
Huh.
Who'da thunk it.

(What?)

(Sam are you serious? What do you mean 'They're more of a bronze-ish hue' OH MY GOD STOP TALKING. No! Don't you dare, Cas - that is irrelevant to my theory - Sam, stop laughing it's legit!)

(What do you mean other angels? You think I turned on angelic X-Ray vision for Zachariah? Who wants to see more of HIM? Seriously Sammy, I don't care.)

(No, I don't know what color Michael's wings are.)

Well apparently Michael's wings are red.
