Emerald may be this year’s color of the year and , but when thinking about refreshing those dull walls, which colors should you avoid?

Color research tells us some colors to avoid. Colors that can be considered, as some researchers note, “eye irritants” and can even cause headaches or mess with your vision.

According to color research, the worst offending color: Yellow as a “pure bright lemon.” “More light is reflected by bright colors, resulting in excessive stimulation of the eyes,”researchers note. “Yellow is an eye irritant. Babies cry more in yellow rooms, husbands and wives fight more in yellow kitchens, and opera singers throw more tantrums in yellow dressing rooms.”

That said, yellow is the first color the human eye tends to notice so in small doses it may be effective. It can help you draw attention to an item when used as an accent color. Also, using yellow in softer tints or in small quantities may not be such a turn-off.

A recent article at Homesessive.com (“Paint Color Trends to Avoid”) pinpointed trendy color combos that may have once been a turn-on that are now becoming a turn-off in home interiors. San Francisco color expert Kelly Berg gives her advice about some trendy color combinations to avoid, such as:

  • “Greige”: The gray and beige combo in a space to create a monochromatic effect. Instead, Berg recommends pulling in some accent colors, likegrassy greens, to make the space more warm and inviting. She also recommends mixing in reflective surfaces, such as glass and metal, to lighten up the room since gray tends to absorb more light than other hues.
  • Chocolate brown and blue: This trendy color combo of a chocolate brown and Tiffany’s blue may be growing tiresome in home interiors. Berg recommends freshening up the look by adding a third color to the mix, such as hot pink, coral, or metallics in silver or gold.
  • Red, Gold and Green: This go-to rustic color pattern also may be beginning to grow stale in interiors. Berg recommends avoiding using all three colors in equal portions when you have a tri-color scheme in a home. She also recommends keeping the saturation levels of the color similar, but not exactly the same to liven up the look.
  • The all white kitchen: A kitchen all in white can look fresh and clean, but the look may be getting overdone and growing dull. Liven it up by pulling in some color from an adjacent space or pull a color from the dishes, Berg says. For example, if the home owner has blue dishes, you might try using deep indigo as an accent color.
