The high-key values of Currier and Ives give it an effulgent, almost bleached quality. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 43.7% of the palette belongs to #E6E6E1, a concentration that makes it the unmistakable visual centre. The most saturated colour, #506E8A, is reserved to 6.0% of the surface, where it acts as a focal punctuation. A value spread of 71 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that Currier and Ives's complete body of work advances.
