Robert Delaunay distributes its values across the middle register, creating harmony without high contrast. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The saturated accent, #D5B948, registers at 7.8% - sparse enough to feel like a deliberate surprise. The full value range is 60 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. Robert Delaunay's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
