Léon Cogniet sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues that Léon Cogniet deploys as the palette's primary energy. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #221C16 at 25.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 3.0% is devoted to #652F18, yet that small allocation delivers the palette's entire chromatic tension. Spanning 47 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Léon Cogniet's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
