Rolf Amstrong keeps values measured and balanced, a hallmark of tonal restraint. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The highest-chroma note - #4A8525 - appears at just 6.7%, deployed as a precision accent against the quieter ground. The full value range is 75 units: broad enough to build convincing three-dimensional form. 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 1 represents one movement in an ongoing chromatic dialogue.
