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.
No pair of colors in this combination reaches a contrast of 3:1, so it is best used without text.
Medium & moderate
Lightness 66 (range 52–74)
Colorfulness 0.105
Average OKLCH lightness (0–100) and chroma (colorfulness).
Triadic
Three hues evenly spaced around the wheel.
A heuristic based on the painter’s color wheel. Wada’s combinations often ignore textbook rules, which is part of their appeal.
Warm & cool
Reds, oranges and yellows count as warm; greens, blues and violets as cool.
