Hans Heysen is strongly light-biased - shadow is suggested rather than declared. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. Only 3.5% is devoted to #9CA2C2, yet that small allocation delivers the palette's entire chromatic tension. 38 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Hans Heysen's complete body of work advances.
