Values in Francis McMellon rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #291A06, is reserved to 6.3% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Francis McMellon's complete body of work advances.
