The 60/30/10 palette plan is a classic color ratio to create balanced, inviting interiors, perfect for small apartments. It means using sixty percent of a dominant color for the space’s base, thirty percent of a secondary color for contrast, and ten percent of an accent color for pops of interest. For example, choose a neutral tone for walls and large furniture, a complementary color for rugs or pillows, and a bold accent for décor or artwork. This formula helps keep your space cohesive and visually pleasing without overwhelming limited square footage.
