The value structure of T. C. Steele is mid-key: quiet, controlled, and cohesive. T. C. Steele tilts toward cool - blues and silver-greys carry the structural weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The most saturated colour, #C3BA5B, is reserved to 8.5% of the surface, where it acts as a focal punctuation. Spanning 52 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. Palette 6 sits within the larger chromatic argument that T. C. Steele's complete body of work advances.
