Green and purple make a good compliment to black and red
For Suits, maybe using important computer code characters as symbols could be cool like # or @, or meaningful symbols we've seen in most quests. Droplets (blood, water, etc.), Hands, Mouse Curser, Circles, and/or a phallic symbol for good measure.
Face characters I'm not sure it would be wise to include quest characters. Everybody will be wanting to get in on that shit as the default, which could create conflict. Perhaps just the main races popular on Tgchan then actual characters. Kobold Queen/Jack, Sergal/Tozol Ace, Another good Jack might be Lohrkes, Furries could go anywhere as anything, cat girls seem to be the most prominent on them, so queen. Maybe a Lizardman or Dragon King. If not a dragon king, a queen. You need dwarfs, good kings and an excellent queen joke.
