design is strongly light-biased - shadow is suggested rather than declared. The palette tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. #C5903F functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). The full value range is 63 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
