For some people, changing colors in a room is like changing your hairstyle. It’s nice to try something different—and it’s easy enough to change back if you don’t like the result. For others, the prospect of switching is a scary proposition.

Painting a room is one of the most affordable ways to make a big change in your home. The only hard part can be the color choice. Looking at the array of paint chips in the store can be overwhelming. Before you head there, narrow down your choices.

Here are some tips for choosing the right wall colors for your home.

Look at your wardrobe. What colors do you like to wear? That’s a big clue to your color preferences. If you’re drawn to neutral colors, you’re comfortable with those soft shades, making this palette a smart choice for your interior walls. If your penchant for lime green or sunshine orange feels too daring for your walls, tone it down a bit.

Inspect your photos, artwork, and other accents. What colors prevail? You chose these decorative pieces for the message they communicate, but was color a factor as well?

Pull the paint color from a print. You might have a favorite pillow, upholstered chair, or even table linens. Zoom in on the shades that might work well on your wall. Take the fabric to the paint store and ask them to match it.

Use a color wheel. See how colors relate to each other. A color wheel gives insight into the hues that work harmoniously together. You might like a monochromatic color scheme, with variations of a particular color (lightness and saturation). A complementary color scheme uses colors that are opposite each other on the color wheel, usually a warm and a cool one (yellow and blue, for example). An analogous color scheme combines colors that are next to each other, like blue and green, or orange and red, and varying shades of those colors. There are several other options for color schemes, but this will get you started. Once you choose the color scheme, you build your palette of specific colors.

Check out color trends. Home décor colors are like fashion. They change with the seasons and the years. Greenery was the 2017 Pantone Color of the Year. The foliage-inspired shade is like a springtime refresh. Home décor watchers are expecting 2018 interior color palettes to move from pastels to more intense hues. With palettes named “Far-fetched”, ”Resourceful”, and “Resourceful”, you might find one to suit your taste.

Think holistically. Your house is a sum of its parts, which includes your wall colors. Make sure you have smooth flow from room to room. This is where organizing a whole-house color palette will help.
