Margaret Macdonald distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #6C4D22 at 9.2% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Margaret Macdonald's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
