Mid-key values give Gregorio Undurraga its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #2F912D, is reserved to 2.8% of the surface, where it acts as a focal punctuation. The palette spans 44 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Gregorio Undurraga arrived at this balance through long practice; the palette carries the weight of that experience.
