John MacWhirter distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #92682D, is reserved to 5.4% of the surface, where it acts as a focal punctuation. At 47 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that John MacWhirter's complete body of work advances.
