Rik Wouters occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #4D667B delivers the chromatic peak at only 1.9% - a small shot of colour with outsized visual impact. 60 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Rik Wouters's instinctive sense of how much of each quality the eye can hold.
