Louis-Jean Desprez distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #6A5137 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.8%). 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Louis-Jean Desprez's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
