Richard Jack sits in the centre of the value range, lending the palette a sense of even, sustained light. Richard Jack builds 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. Only 4.2% is devoted to #BEA070, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 70 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. Richard Jack's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
