The most saturated colour, #B69154, is reserved to 6.4% of the surface, where it acts as a focal punctuation. At 55 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Roderic O'Conor's palette 8 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
