Thomas Moran works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. 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. #A8825A functions as the palette's exclamation mark: highest chroma, lowest percentage (6.2%). The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Thomas Moran's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
