The value structure of Fra Bartolomeo is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Fra Bartolomeo deploys as the palette's primary energy. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. Only 4.7% is devoted to #C17229, yet that small allocation delivers the palette's entire chromatic tension. 71 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 2 of Fra Bartolomeo's sequence - a single chapter in a chromatic story told across many works.
