Response: I think it's just the hotels, since there are few houses in PortoroΓ
ΒΎ. Most of people live in a town nearby, but there are no blue houses there either. I guess no one wants to have a blue house! Houses here are typically white or in pastel colors, only the roofs are red. Houses in a neighborhood are expected to be all in the same color and if you colored your house blue, people would probably think you've gone crazy :D Light colors are also better for the summer here because it gets quite hot and that way the houses don't heat up that much.
