The value structure of George Catlin is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #D8D5BD, is reserved to 9.7% of the surface, where it acts as a focal punctuation. 62 units of value range underpin the palette's structural clarity: the eye always knows where light falls. George Catlin arrived at this balance through long practice; the palette carries the weight of that experience.
