Le Corbusier occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #5889A9 - appears at just 9.7%, deployed as a precision accent against the quieter ground. Value range is moderate at 28 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Le Corbusier's complete body of work advances.
