Values in Theodore Robinson rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #53492C, is reserved to 5.2% of the surface, where it acts as a focal punctuation. The full value range is 56 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Taken together, these qualities constitute Theodore Robinson's chromatic voice - distinctive enough to be read across an entire body of work.
