Mid-key values give Costumbrismo its characteristic quietness - nothing blazes, nothing disappears. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #38291E functions as the palette's exclamation mark: highest chroma, lowest percentage (7.9%). The full value range is 58 units: broad enough to build convincing three-dimensional form.
