James Campbell distributes its values across the middle register, creating harmony without high contrast. James Campbell builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #11151D, registers at 4.5% - sparse enough to feel like a deliberate surprise. 64 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. James Campbell's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
