What is a 60 30 10 color plan in 2025 interior design?

A 60 30 10 color plan divides colors in a room by dominant, secondary, and accent portions: 60 percent is the main color like walls or large furniture; 30 percent covers secondary elements such as sofas or rugs; 10 percent adds accent colors like pillows or lamps. In 2025 trends, use calm foundations with jewel tone accents to create balanced, layered living spaces that feel cohesive and engaging.
