Rembrandt works almost entirely in the lower half of the value scale, privileging depth over brilliance. Warm hues command this palette; Rembrandt favours the reds, oranges, and yellows of firelight and earth. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #E4D29A, registers at 0.9% - sparse enough to feel like a deliberate surprise. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Rembrandt's full range of palettes, group 18 represents one movement in an ongoing chromatic dialogue.
