The high-key values of Thomas Sully give it an effulgent, almost bleached quality. Temperature reads distinctly warm: the reds and earth tones from Thomas Sully carry the compositional weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #0A0201 - appears at just 11.0%, deployed as a precision accent against the quieter ground. A value spread of 79 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 1 of Thomas Sully's sequence - a single chapter in a chromatic story told across many works.
