Edmund Charles Tarbell is high-key - luminous, open, and weighted toward light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #A2634F - appears at just 2.5%, deployed as a precision accent against the quieter ground. 59 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. Edmund Charles Tarbell's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
