Values in Joseph Ducreux rest in the mid-range - neither dramatically lit nor steeped in shadow. Joseph Ducreux tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. #8B673B delivers the chromatic peak at only 3.7% - a small shot of colour with outsized visual impact. 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. In the context of Joseph Ducreux's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
