Fernand Khnopff occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #AE8E68 delivers the chromatic peak at only 10.3% - a small shot of colour with outsized visual impact. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Fernand Khnopff's sequence - a single chapter in a chromatic story told across many works.
