Gerrit Berckheyde occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #7B724E - appears at just 5.0%, deployed as a precision accent against the quieter ground. The full value range is 61 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Gerrit Berckheyde's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
