the urban green bmw looks far too green. the spirant cxar looks alot less green and more grey then that. more a kahki colour then olive

EDIT:
Quick google for ya and came up with this, the colour isnt a BMW colour,
it's actually an OEM nissan colour from a nissan x trail (another good reason to choose it)

it's called Ash Khaki k47

and i believe this is supposed to be the colour mixing chart to make it
