Values in Thomas Sully rest in the mid-range - neither dramatically lit nor steeped in shadow. Thomas Sully orchestrates warmth above all else - reds, ambers, and siennas take the lead. All colours lean toward grey, building depth through value rather than colour punch. At 5.7%, #5B2116 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 68 units: broad enough to build convincing three-dimensional form. This is the light Thomas Sully preferred, made measurable.
