Mid-key values give Armand Guillaumin its characteristic quietness - nothing blazes, nothing disappears. Warmth dominates - the palette of Armand Guillaumin leans heavily on the yellow-orange-red arc of the colour wheel. Mid-range chroma keeps the palette grounded - colourful but not strident. Only 8.6% is devoted to #B5A539, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 65 units of the value scale - a span that creates natural depth. This is palette 4 of Armand Guillaumin's sequence - a single chapter in a chromatic story told across many works.
