Arturo Michelena keeps values measured and balanced, a hallmark of tonal restraint. Warmth dominates - the palette of Arturo Michelena leans heavily on the yellow-orange-red arc of the colour wheel. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #72170E at 7.6% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. 75 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Arturo Michelena's sequence - a single chapter in a chromatic story told across many works.
