Mid-key values give Gregorio Undurraga its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #D15350 claims 30.2% of the surface, functioning as the work's tonal foundation. #B56B66 is not a small accent - at 2.6% it qualifies as a major presence and gives the palette its chromatic identity. The palette spans 42 value units: a measured range that delivers coherence over drama. This is palette 3 of Gregorio Undurraga's sequence - a single chapter in a chromatic story told across many works.
