It does depend on where you live. In southern europe red or orange clay roofing and a range of colors on traditional housing including yellow, pink, orange, etc. makes towns appear much more colorful. In parts of Portugal it's also traditional to paint a broad colorful bar along the bottom of whitewashed outer walls and around doors and windows; the color changes from place to place, and it can be black (I've seen that in the Azores) but also blue, green, scarlet, etc.
