Johann Heinrich Roos occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 1.9% is devoted to #7E482A, yet that small allocation delivers the palette's entire chromatic tension. Spanning 36 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. In the context of Johann Heinrich Roos's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
