Every yin has its yang, and that's true for colors as well. There are lots of ways to come up with a color palette for your room, but some color combinations just aren't intuitively obvious. These colors are opposite each other on the color wheel, but when you put them side by side, the results are stunning.
Copper and Teal
Have a brown leather sofa that you can't bear to part with? Incorporate it into your room by adding teal accents. This is the perfect color combination for a study. A warm brown pairs beautifully with a cooler teal. The look also works well in a formal dining room, where you can paint your walls teal to coordinate with a wooden dining room set. I love the lustrous jewel tone of Cape Verde by Sherwin-Williams.
Apple Green and Rose
Bright green and a softer rose make a fun and surprisingly sophisticated color combination. I love the way these colors make this teenage girl's bedroom look more mature than a little girl's room, while keeping things colorful and full of personality. In pastels, it's a great combination for a kitchen, especially if you want to coordinate painted cabinets with a backsplash.
Tangerine and Sky
This is a really unique and beautiful combination, but you'll want to emphasize the sky blue. Tangerine makes a wonderful, energetic accent color, but it shouldn't be the primary color for your room, especially if you're going with a bright shade like Benjamin Moore's Citrus Orange. Look for warmer shades of orange. I tend to lean towards red-orange rather than yellow-orange, and I usually use a satin or semi-gloss finish for this color to avoid a dull, carrot-like look.
Royal Purple and Butter Yellow
Purple is so playful, and even works as a primary wall color (as evidenced by this picture from the Dutch Boy inspiration gallery). Don't feel like you have to go all in, though. This color palette works for small arrangements, too, like centerpieces for your dining room table or bouquets on the mantle. If you want, try reversing the shades and go with a bright, cheery yellow and a soft, pale lilac or lavender.
Remember, you don't have to commit exclusively to any of these color combinations. Start with a neutral base and add accent colors from there. A fuzzy teal throw blanket can add some much-needed warmth and texture to a leather sofa. A dresser painted with alternating tangerine and sky blue drawers will really pop in an all-white bedroom. Find a color combination you love, and accessorize your room with those colors. Look for things that make you smile when you see them. After all, shouldn't your home be filled with beautiful, cheerful things?
