Mid-key values give Antoniazzo Romano its characteristic quietness - nothing blazes, nothing disappears. Antoniazzo Romano tilts toward cool - blues and silver-greys carry the structural weight. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The highest-chroma note - #EFEDD6 - appears at just 2.6%, deployed as a precision accent against the quieter ground. 60 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. In the context of Antoniazzo Romano's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
