Eugène Grasset occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 12.4%, #EE5638 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 70 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Eugène Grasset's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
