Mid-key values give Gustave Dore its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #2A1617, registers at 6.6% - sparse enough to feel like a deliberate surprise. At 49 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Gustave Dore's sequence - a single chapter in a chromatic story told across many works.
