The value structure of John Leech is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. All colours lean toward grey, building depth through value rather than colour punch. Only 6.0% is devoted to #C7603E, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 71 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. John Leech arrived at this balance through long practice; the palette carries the weight of that experience.
