Oscar Wergeland occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #564732, is reserved to 10.0% of the surface, where it acts as a focal punctuation. The full value range is 55 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 Oscar Wergeland's chromatic voice - distinctive enough to be read across an entire body of work.
