Mid-key values give El Greco its characteristic quietness - nothing blazes, nothing disappears. El Greco builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #D0C3AD, registers at 9.7% - sparse enough to feel like a deliberate surprise. At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. El Greco's palette 7 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
