Mid-key values give Sandro Botticelli its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #90443A delivers the chromatic peak at only 6.8% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. In the context of Sandro Botticelli's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
