John Martin keeps values measured and balanced, a hallmark of tonal restraint. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. Only 11.5% is devoted to #B18252, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. John Martin's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
