Interior designer Demi Adeniran was living happily-ever-neutral in her elegantly understated town house, until the day her 3-year-old daughter said she wanted to "live in a rainbow." But how to incorporate childlike brights with her sedate, grown-up decor? For that she called on her friends at domino. When venturing out of your comfort zone, it's nice to get a second opinion—even if you're a pro.

Living Room (Before)

For six years, Adeniran's Brooklyn home—all soaring white walls and sweeping café au lait curtains—was a welcome respite from her shop, Fabrica. "I urge my customers to go with bold colors all the time," she explains. "I needed my own living environment to be serene, though, so I didn't feel like I was always working." But, inspired by her daughter Antonia's longing for something upbeat, she thought, "'Why not? Maybe it can be serene and happy!"

After scouring design showrooms and stores in Manhattan's Garment District, Adeniran assembled a pile of options, then invited domino's Tom Delavan to be her sounding board. The two whittled down her picks, eventually arriving at a stylish interplay of calming and cheeky hues—making a good thing even better. And Adeniran isn't the only one who thinks so: "Antonia's quite smitten," she says. "She would have liked more pink, but I'm content with it as is. Too much more would have made me a bit nuts!"
