Values in Charles M. Russell rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 4.5% is devoted to #D4A84F, yet that small allocation delivers the palette's entire chromatic tension. 76 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Charles M. Russell's palette 18 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
