The value structure of John Ballantyne is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 6.7% is devoted to #7D4420, yet that small allocation delivers the palette's entire chromatic tension. 72 units of value range underpin the palette's structural clarity: the eye always knows where light falls. In the context of John Ballantyne's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
