The high-key values of Alessandro Grevenbroeck give it an effulgent, almost bleached quality. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #D3C29D functions as the palette's exclamation mark: highest chroma, lowest percentage (7.3%). 71 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. In the context of Alessandro Grevenbroeck's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
