There is one colour that I am not keen on, and that is that 'salmon one' they introduced in 2007. Sorry, no offence intended to anyone that has that colour.
Colour is a personal choice. You have what you like and not what everyone else thinks is nice. My nextdoor neighbour has just bought a bright green car which to say the least is not my chice of colour . However, when buying a car it is a bit like buying a house. How easy could I sell it? Beauty is in the eye on the beholder. Find someone who wants a certain colour and they will pay over and above for it.
