Tarsila do Amaral occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Tarsila do Amaral builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #83853E functions as the palette's exclamation mark: highest chroma, lowest percentage (8.5%). Value range is moderate at 46 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. Tarsila do Amaral's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
