Thomas Moran keeps values measured and balanced, a hallmark of tonal restraint. 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. #B49D6A functions as the palette's exclamation mark: highest chroma, lowest percentage (7.0%). The full value range is 62 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 15 sits within the larger chromatic argument that Thomas Moran's complete body of work advances.
