Clearly Blue/Beige and Blue/Saddle are very nice combinations. The beige and Saddle have the effect of "warming" up the interior environment in terms of color tones. While the gray has a "cooler" color tone, IMO it gives off a slightly more sporty look vs. the more luxurious look of beige/saddle. My only hesitation about the gray is does it look too stark?

I'd love to see some more interior photos of the gray if anyone has any pics.
