William Merritt Chase is high-key - luminous, open, and weighted toward light. William Merritt Chase builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. A single dominant - #E4E8E8 at 30.9% - sets the character of the whole composition. The saturated accent, #C3A13C, registers at 3.5% - sparse enough to feel like a deliberate surprise. 68 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. William Merritt Chase's palette 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
