Diego Velazquez is low-key throughout, a quality associated with Nocturnal Sienna - deep shadows dominate the composition. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #AA9477, is reserved to 2.8% of the surface, where it acts as a focal punctuation. At 59 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities place Diego Velazquez firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. In the context of Diego Velazquez's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
