Felix Vallotton works almost entirely in the lower half of the value scale, privileging depth over brilliance. Warmth dominates - the palette of Felix Vallotton leans heavily on the yellow-orange-red arc of the colour wheel. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. 34.8% of the palette belongs to #170D11, a concentration that makes it the unmistakable visual centre. #E0BB62 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.3%). The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place Felix Vallotton firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 15 sits within the larger chromatic argument that Felix Vallotton's complete body of work advances.
