John Martin sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. #D09E89 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.8%). A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of John Martin's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
