Mid-key values give James Webb its characteristic quietness - nothing blazes, nothing disappears. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #9D6A38, is reserved to 5.1% of the surface, where it acts as a focal punctuation. At 50 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 10 sits within the larger chromatic argument that James Webb's complete body of work advances.
