Romanesque is strongly light-biased - shadow is suggested rather than declared. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. #7D423D functions as the palette's exclamation mark: highest chroma, lowest percentage (5.0%). From deepest dark to palest light, the palette traverses 55 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
