Isidoro Grünhut is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Mid-saturation across the board: the palette has colour character without chromatic excess. A single dominant - #FAE7B2 at 28.4% - sets the character of the whole composition. The highest-chroma note - #B49A63 - appears at just 2.6%, deployed as a precision accent against the quieter ground. At 71 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Isidoro Grünhut's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
