Combination No. 320 as a living room

Painted following the 60-30-10 rule: about 60% wall color, 30% for the sofa, 10% for cushions, throw and vase. A fourth color goes to the rug and curtains; otherwise they stay undyed. Floor and ceiling stay neutral; the print shows the whole palette.

Readable text pairs

No pair of colors in this combination reaches a contrast of 3:1, so it is best used without text.
