The value structure of William Shiels is mid-key: quiet, controlled, and cohesive. William Shiels 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. The most saturated colour, #EBE3C3, is reserved to 9.1% of the surface, where it acts as a focal punctuation. 73 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. William Shiels's palette 2 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
