John Ruskin is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 5.1%, #6F5D50 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 66 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 John Ruskin's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
