The high-key values of Scheiber Hugó give it an effulgent, almost bleached quality. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #DACDB6 at 32.0% - sets the character of the whole composition. The most saturated colour, #D37451, is reserved to 1.4% of the surface, where it acts as a focal punctuation. 72 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 13 sits within the larger chromatic argument that Scheiber Hugó's complete body of work advances.
