Frederick William Burton occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Frederick William Burton orchestrates warmth above all else - reds, ambers, and siennas take the lead. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #5B3031, covers 5.2% of the surface: too much to call an accent, too strong to ignore. The full value range is 65 units: broad enough to build convincing three-dimensional form. This is palette 4 of Frederick William Burton's sequence - a single chapter in a chromatic story told across many works.
