Boleslas Biegas sits in the centre of the value range, lending the palette a sense of even, sustained light. Boleslas Biegas tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #202019 at 35.4% - sets the character of the whole composition. #52673F delivers the chromatic peak at only 4.1% - a small shot of colour with outsized visual impact. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Boleslas Biegas's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
