Mid-key values give Metaphysical art its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The palette gives 30.8% of the composition to a single #140D0B - a decisive chromatic anchor. #774328 delivers the chromatic peak at only 5.8% - a small shot of colour with outsized visual impact. The value range spans 70 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy.
