Dr. Atl keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #CBC0AA functions as the palette's exclamation mark: highest chroma, lowest percentage (2.3%). The full value range is 58 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Dr. Atl's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
