Committing to a bold color choice can be intimidating, so Danielle Coleman, an independent interior designer in Island Park, Illinois, suggests going for it in a small room. “I like more neutral shades in big spaces, but I'll go bold in smaller rooms—that way it's easier to repaint if I change my mind,” she explains. Case in point: Coleman used Behr Premium Plus Ultra in Blue Metal, in a semi-gloss sheen, for the walls and vanity of her master bathroom. “The bath has high white wainscoting and white marble tile, so I wanted a dark color to warm things up and provide a stark contrast,” she says. Designer-to- DIYer tip: “Having the walls match the vanity makes the vanity feel that much more custom,” Coleman says.
