Blue door, white wall
Blue and white are the definitive colours of Santorini. The white walls are dazzling and the blue stands out perfectly on them. It is no wonder that this awesome place merges so effortlessly into the sky. They merge together very well too. And of course, you can't go wrong with black & white. See the blue domes in Imerovigli, Firostefani and Oia.
