Low-key values are the structural spine of Lemuel Francis Abbott, giving it gravity and atmosphere. Temperature reads distinctly warm: the reds and earth tones from Lemuel Francis Abbott carry the compositional weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #131011 claims 52.3% of the surface, functioning as the work's tonal foundation. The saturated accent, #3F2215, registers at 3.6% - sparse enough to feel like a deliberate surprise. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This tonal restraint is characteristic of the Lemuel Francis Abbott approach: colour serves light, not the reverse. This is palette 10 of Lemuel Francis Abbott's sequence - a single chapter in a chromatic story told across many works.
