Eugeniusz Zak is high-key - luminous, open, and weighted toward light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 29.1%, #C2DB89 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #2A5561 - appears at just 6.8%, deployed as a precision accent against the quieter ground. At 43 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Eugeniusz Zak's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
