Antonello da Messina keeps values measured and balanced, a hallmark of tonal restraint. Antonello da Messina tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 26.0% of the palette belongs to #D4D6D5, a concentration that makes it the unmistakable visual centre. #323B66 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.6%). 64 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 6 sits within the larger chromatic argument that Antonello da Messina's complete body of work advances.
