Martin Johnson Heade occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is measured and controlled, giving the palette presence without visual aggression. The most saturated colour, #C15C3C, is reserved to 4.3% of the surface, where it acts as a focal punctuation. The full value range is 68 units: broad enough to build convincing three-dimensional form. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. Martin Johnson Heade's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
