Proto Renaissance occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The artist keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The most saturated colour, #AE4336, is reserved to 4.7% of the surface, where it acts as a focal punctuation. 46 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The palette reads as an Impressionist one - light-biased, chromatically direct, and built on temperature contrast rather than value opposition.
