Gustave Jacquet sits in the centre of the value range, lending the palette a sense of even, sustained light. Gustave Jacquet tilts toward cool - blues and silver-greys carry the structural weight. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The saturated accent, #C7B174, registers at 7.5% - sparse enough to feel like a deliberate surprise. 62 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 Gustave Jacquet's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
