Gregorio Undurraga works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 9.5%, #BEB89A carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The 22-unit value range keeps all colours in close tonal proximity, creating the unity of a single-light-source interior. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that Gregorio Undurraga's complete body of work advances.
