What the 60-30-10 rule means
It's a proportion, not a law. About 60% of what you see is the dominant color: walls and the biggest rug. About 30% is a secondary color on large pieces like the sofa, curtains or cabinets. The last 10% is an accent on pillows, art and lamps. Keeping one color in charge is what makes a room look planned instead of busy.
Why the contrast check matters
Two colors that look different as chips can merge on a wall across the room. We measure each pair with the WCAG contrast ratio. An accent under 3:1 against the walls tends to disappear; a secondary under about 1.3:1 reads as the same color. The numbers come from the on-screen color, so treat them as a guide and confirm with real samples.
Where the paint colors come from

Questions
What is the 60-30-10 color rule?
A decorating proportion: about 60% of a room in a dominant color (walls), 30% in a secondary color (large furniture, textiles) and 10% in an accent (small decor). It keeps one color in charge so the room feels cohesive.
Are these real paint colors?
Yes. Each role is matched to the closest real color from Sherwin-Williams, Benjamin Moore or Behr in our library, with the brand code. Screen colors are approximate, so always check a physical sample in your light.
Which color should go on the walls?
Usually the lightest, softest color (the 60% dominant). Darker or more saturated colors work better as the 30% or 10% unless you want a moody, color-drenched room.
Do I need an account?
No. The generator is free and runs in your browser. Only the optional AI render of the palette on your own room photo needs a free account.
