Thomas Hill keeps values measured and balanced, a hallmark of tonal restraint. Thomas Hill builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #D0C696 - appears at just 6.6%, deployed as a precision accent against the quieter ground. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Thomas Hill's full range of palettes, group 10 represents one movement in an ongoing chromatic dialogue.
