Gregorio Undurraga works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Gregorio Undurraga builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is measured and controlled, giving the palette presence without visual aggression. 26.7% of the palette belongs to #C8BEAC, a concentration that makes it the unmistakable visual centre. #1F8027 delivers the chromatic peak at only 3.9% - a small shot of colour with outsized visual impact. Value range is moderate at 48 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Gregorio Undurraga's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
