Tubism sits in the centre of the value range, lending the palette a sense of even, sustained light. The palette tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #D0A130, is reserved to 4.7% of the surface, where it acts as a focal punctuation. The value range spans 69 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
