George Catlin is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #9D4935 - appears at just 7.5%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 67 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. George Catlin's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
