Erasmus de Bie distributes its values across the middle register, creating harmony without high contrast. Erasmus de Bie tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #643D2C functions as the palette's exclamation mark: highest chroma, lowest percentage (1.7%). Value range is moderate at 45 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Erasmus de Bie preferred, made measurable.
