When we do interior painting, we always go 3 shades lighter on the ceiling in comparison to the wall color on the sides. If its too bright, opt for white.
Pick a Flow-Through Paint 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,” says Kelly 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 to have that dominant color in your space.”
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.
Most paint companies have a "pure white" or "ultrawhite" paint, which will give you a very crisp and clean look in the kitchen. But you can also go with a shade of white that has a tiny touch of yellow, brown or gray, which will warm up or cool down the white and add a little life to it. Note: The differences in the paint swatch appearances will vary depending on your monitor, but this can give you a starting point at the paint store. As always, be sure to paint a large test area and look at it through the day and week, with natural and artificial light, before making a final decision.
