The beauty of a home with white walls is that you can incorporate so many other bold colors and patterns, or go more calm and sedate, or really do whatever you like. It's very versatile. If you keep the walls white, then pick two or three accents colors per room. Like in your living room you could have a pretty turquoise vase, throw pillows that are turquoise and green, and curtains that are turquoise, yellow and green, and in another room you could mix chocolate brown and robin's egg blue. You don't have to go all out. Just a few pops of color will do. My old room was cloud white, and I used a lot of pretty jewel-like colors. We lived in a condo in Chicago then, and my room was small. My room felt bigger being white. My last room was a very pale sunshine yellow, and I loved it at first and then I hated it. It sort of looked like cat pee to me after a while. Now my room is fuchsia. I freaked out when I finished it because it's so bold, but now I love it. It looks so crisp with my white furniture and bedding. Idk how old your daughter is and if she's looking for new bedding but Teen Vogue has an amazing new line at Macy's. It's much better than you'd expect it to be.
Painting is super easy. Use frog tape.I don't know why you don't paint. It's not that hard putting colors together, either. It's really fun. I helped my grandparents redo their entire downstairs and it looks awesome. I just went through the Domino Magazine Flickr group, Apartment Therapy, and different blogs to get ideas. You'll feel really proud when you just put it all together, and it doesn't take that long.
Foyer, downstairs hallway, stairs and landing: a sophisticated turquoise blue called Wythe Blue from Benjamin Moore. It's the exact same color used in the house on "Mad Men." My nana liked that house so I looked it up.
Living room: very gentle, creamy gray with ivory paneling.
Dining room: wallpaper
Kitchen: wallpaper
Great room: pale turquoise that's in the same family as the Wythe blue.
Downstairs bathroom: pale lavender gray. It's the color of my favorite MAC eyeshadow. I just brought it into Home Depot and they color matched it. That bathroom is unusually big, so the color works well and makes it spa-like calm.
Guest rooms: they haven't been redone in forever. There's some seriously craptastic wallpaper from the 90s going on in there.
My grandparents room: wallpaper (but it's really nice wallpaper)
My room: fuchsia
My bathroom: very, very light, watery aqua
