Values in George Luks rest in the mid-range - neither dramatically lit nor steeped in shadow. 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. The chromatic peak belongs to #DEC496, and at 4.9% it dominates, not decorates. The full value range is 60 units: broad enough to build convincing three-dimensional form. In the context of George Luks's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
