John Martin works almost entirely in the lower half of the value scale, privileging depth over brilliance. Warm hues command this palette; John Martin favours the reds, oranges, and yellows of firelight and earth. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #714107, registers at 7.9% - sparse enough to feel like a deliberate surprise. At 36 units across the value scale, the palette keeps contrast readable without letting it dominate. Together these qualities place John Martin firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. In the context of John Martin's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
