The value structure of John Bradley is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Mid-range chroma keeps the palette grounded - colourful but not strident. The most saturated colour, #B16213, is reserved to 6.7% of the surface, where it acts as a focal punctuation. Value range is moderate at 43 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of John Bradley's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
