When you’re mixing different yellows in a room, as a rule, more is more.

Err on the side of excess -- with just a couple of different yellows, you risk a mismatched effect. “You can combine two shades of a color pretty easily, but if you add a third, it gets more difficult,” Jayne says. “When you add a fourth and fifth, it gets easier again.”

In this space: A mélange of yellows mingle in this living room, part of the Southern Accents 2008 Showhouse at Regents Park. Although the shades on the walls, sofa, and chairs are in the same family, they’re diverse enough to add a subtly layered effect. Deep browns ground the palette.
