Style Secret: Colorful TileHand-painted, brightly patterned tiles are a Southwestern signature. Their distinctive designs and happy colors lend a festive air, and they hint at the artisanal character that defines a Southwestern space. Use them to line the edges of countertops, stud backsplashes or cloak an accent wall. But remember ... Don't mix too many different tlle patterns in a single room — otherwise they'll compete with one another and add up to visual chaos. And as a rule, these tiles are best used sparingly so that they don't overtake the space. The planter box in this courtyard has just enough presence to make it an engaging focal point.
