Values in Agnes Lawrence Pelton rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #3F5C37 - appears at just 7.4%, deployed as a precision accent against the quieter ground. At 50 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Agnes Lawrence Pelton's sequence - a single chapter in a chromatic story told across many works.
