Mid-key values give Fra Angelico its characteristic quietness - nothing blazes, nothing disappears. Temperature reads distinctly warm: the reds and earth tones from Fra Angelico carry the compositional weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The highest-chroma note - #BD913D - appears at just 5.2%, deployed as a precision accent against the quieter ground. The palette spans 52 value units: a measured range that delivers coherence over drama. Palette 4 sits within the larger chromatic argument that Fra Angelico's complete body of work advances.
