Ferdinand Hodler is high-key - luminous, open, and weighted toward light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #B9AF8D, is reserved to 1.5% of the surface, where it acts as a focal punctuation. Spanning 35 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Ferdinand Hodler's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
