alskdjf omg alright okay yeah!
So Wei Wuxian's godly design is very much a sort of fusion of his Yiling Laozu looks (primarily black with red and grey/silver) and some elements of TGCF's general godly character design (mostly the manhua and the in-book art. I love the donghua's character design but they're very much made for simplicity and I think the gods are ostentatious enough to want a bit More to their looks, usually.) with just a splash of Jiang aesthetics because he's got a fondness for lotus.
WHICH IS TO SAY.
I imagine his robes are a deep black with silver embroidery on the outside. His inner robes are, of course, red, and the inner robe sleeves are narrow and long enough to tuck into his bracers. The black outer robes, with as many layers as you like, are long, but the sleeves are typically only half-sleeves because at the start of the story his main thing is archery. (Similar to donghua Pei Ming's sleeves). (He has a black mulberry bow with silver inlay, red leather around the handle, and a string made partially out of his own hair aslkdjf. Quiver is a black and silver back quiver of some sort and the arrows are fletched with black, with red and silver strings. They're very fancy and come back to him, so he made them look good (literally made them, he spent two years making this spiritual weapon).)
Black trousers and boots, and silver armor with smoke designs on his chest, bracers, and pauldrons (shoulder covers). The armor's not overly elaborate or bulky, and fits his form well.
Wide belt. Silver and/or red accents, black if there's leather.
He has. Dark red eyes, because gods and funky eye colors are my jam, and they glow red when he's really using big power. He also has long hair he wears half-up (A topknot like cql!Wei Ying, but better and also longer, maybe a little wavy. I'm fond of his having bangs, too, so it's not ALL pulled back), and on his head is a silver lotus crown on fire. Very tall flames. Pointy at the top.
Because I like being extra and therefore he does, too, he's taken a few aesthetic tips from Hua Cheng and participates in a bit of hair-braiding up top, nail-painting, and some makeup around the eyes, and he's got some sort of dangly silver earrings I think.
When he's really going for dramatics, he has a whole-ass black cloak on that swishes Very Nicely.
All of this sounds very specific, but it's really more about the Vibes. He has multiple outfits, so if you do end up creating something and have a Different Idea, then by all means roll with it! The Palace of Yiling's colors are black, red, and silver primarily (as he's still the Yiling Laozu) and he does keep his goth kid tendencies, even in the Celestial Court.
His magic is red and gold uwu until he re-learns how to manage using guidao when his body is literally made of divinity, in which case it's red and black when he's using that.
Thank you for giving me an opportunity to talk about god!Xian uwu.
I love him so much and he's been cooking for so long in my brain. Of course he wears simpler clothing than this in the mortal realm, but his Godly Look is definitely something I've had a lot of fun coming up with.
