Values in Luca Signorelli tilt decisively toward white, giving the palette its luminous character. Luca Signorelli keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 4.9%, #CCB172 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 63 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 1 of Luca Signorelli's sequence - a single chapter in a chromatic story told across many works.
