The value structure of Gustave Moreau is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Gustave Moreau deploys as the palette's primary energy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 6.5% is devoted to #7B3E2D, yet that small allocation delivers the palette's entire chromatic tension. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Gustave Moreau's palette 11 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
