Color study
A dictionary of color
Background, surface, text and accent, taken from one of Wada’s combinations.
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.
