Values in John Duncan tilt decisively toward white, giving the palette its luminous character. John Duncan builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #B66B46 - appears at just 1.8%, deployed as a precision accent against the quieter ground. Spanning 36 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. John Duncan's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
