What are your favourite colours? Not car colours, or paint colours, but the colours you like to wear; the colours that make you happy when see them in a shop window. If watermelon red, lemon yellow, chocolate brown, pewter grey, pastel pink, purple, orange, green, blue (peacock, navy, sky ...), black, white, etc. etc. do it for you, now's the time to admit it.
And you don't have to pick just one. :-)
Lumps of coal in the stockings of people who don't comment. ;-)
