Frans de Hulst occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Frans de Hulst builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #403813 - appears at just 4.8%, deployed as a precision accent against the quieter ground. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 5 sits within the larger chromatic argument that Frans de Hulst's complete body of work advances.
