The top three favourite car colours in the UK in 2016 were white, black and grey (in that order). White has been the best seeing colour for four years which is interesting because it never used to be popular in the UK. Car salesman used to refer to the colour as three-week white because it took three weeks longer to sell a white car compared with other colours. But it’s 10 years now since a chromatic colour was number 1.
