Rolf Amstrong distributes its values across the middle register, creating harmony without high contrast. Rolf Amstrong builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #A7965D functions as the palette's exclamation mark: highest chroma, lowest percentage (5.4%). 70 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. In the context of Rolf Amstrong's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
