Any color you pick should have a green hue as it is easiest on the eyes. All colors can be classified as either
red/green, blue/yellow and light or dark. So if you pick a beige make sure it is green/yellow in tone as it will be the most soothing on your eyes. Red tones are very shocking on the eyes and that is why stop signs are painted red. It will be easy for you to see if you have all the color chips together. I have been formulating automotive colors for 25yrs and color does have a big impact on how your going to enjoy your room. Good luck!
