The palette of Odilon Redon sits in the lower register of the value scale - dense, contained, and weighted. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #BA7B3F, registers at 3.9% - sparse enough to feel like a deliberate surprise. The value range of 51 units sits in the comfortable middle: enough depth, enough light, neither extreme. This tonal restraint is characteristic of the Odilon Redon approach: colour serves light, not the reverse. This is palette 21 of Odilon Redon's sequence - a single chapter in a chromatic story told across many works.
