Values in Precisionism tilt decisively toward white, giving the palette its luminous character. Built on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #B25B50, registers at 2.3% - sparse enough to feel like a deliberate surprise. The full value range is 66 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
