Charles Demuth is high-key - luminous, open, and weighted toward light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #C3A27F - appears at just 5.5%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 59 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Charles Demuth's sequence - a single chapter in a chromatic story told across many works.
