Values in Gilbert Jackson rest in the mid-range - neither dramatically lit nor steeped in shadow. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. All colours lean toward grey, building depth through value rather than colour punch. Only 7.3% is devoted to #6D2B19, yet that small allocation delivers the palette's entire chromatic tension. 67 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Palette 1 sits within the larger chromatic argument that Gilbert Jackson's complete body of work advances.
