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. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 10.0% is devoted to #4C68A8, yet that small allocation delivers the palette's entire chromatic tension. 39 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. In the context of Limbourg brothers's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
