Gregorio Lopes occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Gregorio Lopes 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. #C68E3A functions as the palette's exclamation mark: highest chroma, lowest percentage (7.7%). The full value range is 66 units: broad enough to build convincing three-dimensional form. The palette reads as an Impressionist one - light-biased, chromatically direct, and built on temperature contrast rather than value opposition. Gregorio Lopes arrived at this balance through long practice; the palette carries the weight of that experience.
