Values in Walter Sickert rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #A78A50 - appears at just 3.6%, deployed as a precision accent against the quieter ground. Value range is moderate at 46 units - enough contrast for legibility, not so much as to fragment the tonal unity. 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 1 of Walter Sickert's sequence - a single chapter in a chromatic story told across many works.
