Hmmm...off the top of my head.
Kasumi- Pastel Pink (pastels in general)
Ayane- Lavender
Hayte- Dark Red
Ryu- Black
Zack- Lime Green (neons in general)
Jann Lee- Red
Leifang- Red and Gold
Helena- Rose Gold
Brad- Mossy green (earthy colors in general)
Hitomi- Cherry Pink
Christie- Silver and Red...
Maybe we can bully them into better casting like we did with the visuals to the Sonic movie (except Jack Black, we can keep him)
I'll wait for a trailer, maybe it won't be so bad
