Ozias Humphry distributes its values across the middle register, creating harmony without high contrast. Ozias Humphry tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 42.8%, #050505 functions less as a colour accent and more as a complete atmospheric environment. Only 3.3% is devoted to #AD815B, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 71 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Ozias Humphry's complete body of work advances.
