The value structure of Limbourg brothers is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 26.6%, #686762 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #A57C45 - appears at just 8.9%, deployed as a precision accent against the quieter ground. 35 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 12 of Limbourg brothers's sequence - a single chapter in a chromatic story told across many works.
