I've seen some Audis that looked fairly handsome in browns tones.
Cars We Drive! - Page 210
I was talking about green, but it's same goes for brown and a couple other colours.
the color depends on the car
some look good in a 'toy color', some need something more staid
imo it also depends on the clime: a bright 'toy' color might work well in AZ or CA, but not so well in the Yukon or Siberia lol
some of the new 'earth tones', copper, bronze, etc., look alright...
Audi makes a few great brown interior (nougat and balao) but needs matched to the exterior
on the A8 they have only 1 brown (actually metallic beige)
not sure where this fits in :D
