Values in Martin Johnson Heade rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Mid-saturation across the board: the palette has colour character without chromatic excess. The highest-chroma note - #231420 - appears at just 9.3%, deployed as a precision accent against the quieter ground. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 1 of Martin Johnson Heade's sequence - a single chapter in a chromatic story told across many works.
