Jan van Eyck occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Jan van Eyck builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. At 5.2%, #8D3D27 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 79 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Jan van Eyck's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
