The value structure of Masaccio is mid-key: quiet, controlled, and cohesive. Warm hues command this palette; Masaccio favours the reds, oranges, and yellows of firelight and earth. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The most saturated colour, #C44435, is reserved to 4.4% of the surface, where it acts as a focal punctuation. 76 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Masaccio's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
