Pieter Casteels II occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #D1BE89 - appears at just 4.0%, deployed as a precision accent against the quieter ground. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is the light Pieter Casteels II preferred, made measurable.
