I like the Kalahari Interior and like hotlap posted the suede knee bolsters help step it up a notch. But in my opinion the exterior color affects how much/ what color interior compliments it.

Kalahari with Black, Gray, Silver, Blue Velvet, White Exterior
Possibly Hyper Blue, Garnet Red
But not Yellow or Red Hot
(again, in my opinion)

Red Accent interior with Black, Red Hot, Gray, White, Silver, Blue Velvet
Not Hyper Blue, Garnet Red, Yellow

White Accent interior with Black, White,
Possibly Red Hot, Hyper Blue, Blue Velvet, Gray, Garnet Red
Not Silver, Yellow

Grey or Black interior work with all of them, The 2 exceptions I think are;
Yellow with Grey interior (i don't think compliment as well as black int.)
Gray on Gray (might be too much gray for me, i think i'd want something to break it up)

Just my 2cents
