Johann Jakob Strutt occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #443924 - appears at just 11.7%, deployed as a precision accent against the quieter ground. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Johann Jakob Strutt preferred, made measurable.
