Designer Barry Dixon will offer decor advice at Grosse Pointe Farms show

Or, you find something that plays against the style on purpose. If one thing is modern — simple, minimal, angular and blocky — then put something effusive, carved and curvilinear next to it. Such juxtaposition highlights diversity, sort of like masculine and feminine. In a strange way, you’re showing off every nuance of each piece — you see all of its qualities. At the same time, you create an interesting balance. It’s almost like a good marriage — often people pick a mate who’s everything they’re not and together they’re successful.

The thing you can’t do is mindlessly throw things together and call it “eclectic.” That’s often a catchall phrase when things are paired without reason or purpose.

Describe your color philosophy.

It’s all about the psychology of a room — what you want that room to be. If it’s a chill-out room, you want colors that are calming: pale greens, grays, quiet blues — serene tones that you see in a spa. If you need to be awakened, in a kitchen, maybe you need orange and yellow, or red and white checks.

What inspires your palette?

I’m inspired by the colors of nature, and I love to bring the outside in — whatever I see through the window of a home. If I’m in the Caribbean, I’m seeing turquoise water and chartreuse banana leaves. In Manhattan, I’d use gray, black and silver in a penthouse, but I wouldn’t use those colors in my Virginia farmhouse.

Just as eyes are a window to the soul, you have to look through the eyes of the house, the windows, to … make it feel like it has an honest connection to the world. They’ll unite interior space to exterior and almost make the inside bigger. It really does happen — any time you blur a boundary you open a space.

Any tips to transition a home from winter to spring?

I just do furniture arrangement — a little less fireplace-centric, and a little more view. Put the big sofa so that it looks out at the view, angle the chairs so they look out at the flowers.

Bring fresh flowers inside to remind us of the season — don’t use spring daffodils and tulips in winter.

What one change gives the most bang for the buck?

Bring color to your life. Color changes everything. Change the color behind you on the wall, bring in some bright pillows. It’s always the quickest fix and people can do it themselves.

What’s a typical mistake and how can we avoid it?

People buy gigantic sets of things that all match; the entire room has such a specific look that it’s boring. You wouldn’t wear all denim. You’ve got to break it up and mix: mix the high and low, the old and new, the formal and informal and you’ve got something that feels modern. It’s the mixing of things that makes it personal — that’s how you put the “you” in your home.

Pick a chair from Pottery Barn and an antique console from the antiques show and mix them together. The expensive piece brings up the inexpensive piece, and the common piece makes the rarefied piece approachable. If everything in the living room is all treasured things, it feels stilted and on display, not relaxed. Mixing knocks it off the “don’t touch me” pedestal and makes it hospitable and approachable.

Are some of us hopeless?

I don’t think anyone is hopeless. You just need to look at everything with an open eye. Some people get too hung up on the way things have always been. Designers come in with a fresh eye — we’re not married to the fact that the buffet has to go in the dining room because it came with the table 20 years ago. Move the buffet to the big foyer in your big new house. Change the fabric on the two arm chairs and move them to the living room fireplace. Find a beautiful pair of antique chairs and use those in the dining room instead.

You’ve not only broken up the set, you’ve united three separate rooms — there’s a unifying aesthetic. People will think you got all new furniture and everything feels fresh.
