Harriet Backer occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #756939 delivers the chromatic peak at only 6.9% - a small shot of colour with outsized visual impact. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Harriet Backer arrived at this balance through long practice; the palette carries the weight of that experience.
