John Singer Sargent distributes its values across the middle register, creating harmony without high contrast. Warm hues command this palette; John Singer Sargent favours the reds, oranges, and yellows of firelight and earth. All colours lean toward grey, building depth through value rather than colour punch. #9791BB delivers the chromatic peak at only 4.1% - a small shot of colour with outsized visual impact. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of John Singer Sargent's full range of palettes, group 13 represents one movement in an ongoing chromatic dialogue.
