Blue is the colour! Whether duck egg, midnight, navy or teal, the estate agents with years of selling houses under their belts deem it the most enticing (12 votes). Second is green (8) in sage, lichen, royal and olive. Joint third with seven votes each are grey (in all its shades) and black. Next is plain wood (3) red (2), yellow (2) and cream, white and dark aubergine (1 each). Lastly, whatever the colour, it’s clearly time to buy shares in Farrow & Ball.
