Alan Stephens Foster keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #95442A - appears at just 3.9%, deployed as a precision accent against the quieter ground. 71 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Alan Stephens Foster's sequence - a single chapter in a chromatic story told across many works.
