One simple way to create a cohesive feel is to use a consistent paint color on the walls of connecting spaces. “Particularly in homes that have more of an open floor plan, it’s best to choose one color that is going to serve as your main color or your neutral,” saysKelly Porter, an interior designer based in Washington, D.C. “That doesn’t mean it has to be beige or white or gray. But the foyer, the hallways and that main connector room should all be the same color because you want that to have dominant color in your space.”

How to Choose the Paint Color You Really Want

San Francisco interior designer and color expert Jennifer Ott frequently works with clients who want more variety in their wall colors. When that is the case, she suggests considering sightlines. When you’re standing in the living room, what other rooms will you see? If you have a view into the kitchen, the dining room and the foyer, then the colors for those spaces need to work well together. “It can start to look really wacky if you have a different color scheme in each room,” Ott says.

One way to increase the likelihood that a color scheme flows from room to room is to limit yourself to colors in the same temperature family. “Some people will stick to a warm color palette — reds and oranges and yellows — or a cool scheme — grays and greens and blues,” Ott says.

For wall paint, you can ask the paint store to create a “tint” of a particular color, perhaps knocking down the main color by 50 percent, which the mixer will do by adding white. “They can create a lighter or darker version of it,” Ott says. “That’s a good way to unite without putting the same color everywhere.”

“I also tell people if they’re going to do their wall in this color, go two or three shades lighter for your ceiling so it doesn’t look like a sore thumb because you painted it white,” says Keith Wardlaw of Plus Modern Design in Kansas City, Missouri.

Paint decks can also be a good inspiration source for finding colors that work well together.

The Right Way to Test Paint Colors

Accessories are a less expensive way to introduce dramatic colors than purchasing a couch or rug in the same tone, and they’re also easier to swap out should you tire of a color. Limiting bold colors to accessories also helps you avoid the shocking effect that can happen when a dramatic shade is painted on all four walls. “The key is finding a way to inject the color that makes rooms interesting and exciting without feeling like you need to escape,” Ott says. Bright color is good when you want to highlight a piece worthy of notice.

Accents colors can change from room to room, but continuing one consistent color throughout the home can help create a sense of continuity. “Let’s say you have green and blue in your living room,” Porter says. “Perhaps for the dining room, you use one of those two colors, maybe just the blue. Or you could do blue and yellow. So the blue is what will tie those rooms together.” The two rooms pictured are from the same home and illustrate this principle.

Strategies to Create Color Flow Throughout a Home — a Case Study

Another way to create a cohesive flow from room to room is to think of the palette for your home as a math problem. “Use a base color that you really like as 60 to 70 percent of what you’re going to paint for your interior,” Wardlaw says. “Your next color needs to be 25 to 30 percent. Then you can do your accents of 5 to 10 percent.”

In this photo, which shows one of Wardlaw’s designs, gray is the 60 percent color, blue the 25 percent, orange about 10 percent and brown maybe another 5 percent. “I really try to make people only go with about three colors, four at the max — at least on the interior,” Wardlaw says. “Otherwise it just feels chaotic.”

To pull the colors throughout the home, you might use a variation on the scheme in an adjacent dining room. The walls might be painted blue, and perhaps gray could be used as an accent, with a few small orange accessories providing the 10 percent dose of color. “As long as you keep it cohesive throughout your entire home, it’s going to make more sense,” Wardlaw says.

Porter, who does a lot of color consultations, says her clients tend to know what color they want to use in terms of color, but need validation that the shade they are considering will produce the desired effect. Recently, the designer did a long-distance consultation with a client who passionately loves orange. “The colors she was telling me about were very bright and childlike,” Porter says. The designer suggested a more adult rusty orange instead. “She tried it and loved it,” Porter says.
