Low-key values are the structural spine of Edward Bower, giving it gravity and atmosphere. Edward Bower tilts toward cool - blues and silver-greys carry the structural weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #492F17, is reserved to 4.0% of the surface, where it acts as a focal punctuation. A value spread of 57 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This tonal restraint is characteristic of the Edward Bower approach: colour serves light, not the reverse. Palette 4 sits within the larger chromatic argument that Edward Bower's complete body of work advances.
