Mid-key values give Alphonse Mucha its characteristic quietness - nothing blazes, nothing disappears. Temperature reads distinctly warm: the reds and earth tones from Alphonse Mucha carry the compositional weight. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #84321C, registers at 4.7% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 64 units of the value scale - a span that creates natural depth. Palette 13 sits within the larger chromatic argument that Alphonse Mucha's complete body of work advances.
