I'd love to see a black and gold art deco/elegant theme. The base color would be black with gold accents. This could be a recolor of the default poses, or feature individualized poses, with pets looking snooty, dignified, elegant, aloof, lounging, etc, with horns, claws, scales, feathers etc looking like they've been gilded, and fancy, gold art deco patterning. I can't draw, but here's a little collection of some of the themes I picture it having.

I love art deco and related styles. Never would of thought of it for a pet color but now I want this so bad.
Oooh. Oooooooooooooh.....!! Yes, please! Very much love this idea! I know just the pet I'd use it on too. :D :D
ooh ok this could maybe work as a sort of centropolis-based color, like how we have colors thematically and lore-wise based in other regions (glade for peka, glacier for arctic frost, galactic & steamwork for atebus, graveyard for shadowglen, darkmatter for darkside...), considering centropolis is inspired by major cities like new york, which has a rich history of art deco architecture—and in fact the item directory building is designed in this style, likely after the chrysler building specifically.
maybe it could be tied in with saggitarius as a sort of "luxury" color (in fact maybe it could be called luxe or luxurious, or opulent or something like that). might be cool if the pets' anatomy & posing were also slightly stylized into the more geometric/angular look of that sort of art.

I would love to see this. ;a;
