Mid-key values give Louis Leopold Boilly its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The most saturated colour, #D6B54A, is reserved to 7.5% of the surface, where it acts as a focal punctuation. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Taken together, these qualities constitute Louis Leopold Boilly's chromatic voice - distinctive enough to be read across an entire body of work.
