Guillaume Seignac sits in the centre of the value range, lending the palette a sense of even, sustained light. Guillaume Seignac builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #6B5337 delivers the chromatic peak at only 7.1% - a small shot of colour with outsized visual impact. 54 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of Guillaume Seignac's sequence - a single chapter in a chromatic story told across many works.
