Henry Stacy-Marks occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Henry Stacy-Marks balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #5B300F functions as the palette's exclamation mark: highest chroma, lowest percentage (3.7%). At 60 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 6 of Henry Stacy-Marks's sequence - a single chapter in a chromatic story told across many works.
