80/20 Rule

Remember that intense colors should be used sparingly to punctuate a room rather than to define it completely. The universal design recommendation is to use 80% neutral colors and 20% stronger colors. The concept is similar to that of makeup: red lipstick is applied to only a tiny portion of a woman's face. The rest is light and neutral. That's also how you balance rooms. The 80/20 rule states that colors are crucial in every room. And whether or not a room attracts attention is entirely dependent on them. As a result, they look great on accent surfaces like walls, soft rugs, large curtains, and even chairs. Colors are just strong enough to give a room everything it requires to be appealing. And it's made up entirely of solid colors (20%) and neutrals (80%).
