Claude-Joseph Vernet occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Claude-Joseph Vernet tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #9E7B4C - appears at just 3.2%, deployed as a precision accent against the quieter ground. Value range is moderate at 50 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Claude-Joseph Vernet's sequence - a single chapter in a chromatic story told across many works.
