Darkness anchors John Pettie; light is rationed, creating dramatic contrast rather than open air. John Pettie builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. 33.1% of the palette belongs to #0E0D0B, a concentration that makes it the unmistakable visual centre. #E4D3A1 delivers the chromatic peak at only 1.4% - a small shot of colour with outsized visual impact. 71 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Together these qualities place John Pettie firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. This is palette 8 of John Pettie's sequence - a single chapter in a chromatic story told across many works.
