Jérôme-Martin Langlois works almost entirely in the lower half of the value scale, privileging depth over brilliance. Yellow, ochre, sienna: warm hues that Jérôme-Martin Langlois deploys as the palette's primary energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #110C08, takes 38.5% of the total area, establishing the overall mood before any other hue is introduced. Only 4.2% is devoted to #8D3316, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 72 units: broad enough to build convincing three-dimensional form. Together these qualities place Jérôme-Martin Langlois firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Jérôme-Martin Langlois's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
