like the design of the ships hull, it seems that interior sets reflected the car interiors at the time they were made (Next G bridges were all tans and beige). however, I just CAN'T see a Charcoal grey, black, and silver bridge scheme. EWWW.
the problem is, there's not much in the way of Neutral colors other THAN the "beige" set and the "greys" set, and they're overused. and almost any other color scheme is too Garish to stand. it's gonna be a hard decision.
