Charles Sillem Lidderdale keeps values measured and balanced, a hallmark of tonal restraint. Charles Sillem Lidderdale tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #C67951 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). At 53 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 2 of Charles Sillem Lidderdale's sequence - a single chapter in a chromatic story told across many works.
