Tubism keeps values measured and balanced, a hallmark of tonal restraint. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #E5E2D6 at 26.4% - sets the character of the whole composition. Only 5.8% is devoted to #233850, yet that small allocation delivers the palette's entire chromatic tension. 62 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.
