Charles Brooking keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #332C20, is reserved to 8.9% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Charles Brooking's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
