Hamilton is a light blue-green from COAT. As a premium paint, it’s a popular colour to seek out close matches and value-brand alternatives to.
Powder Blue by Farrow & Ball is the closest match from any other brand (near-identical) — and it holds Hamilton’s lightness, warmth and saturation alike. The closest value-tier option is Aquamarine Dream by Johnstone's (near-identical), just as true to the original. 3 of the 8 other brands have a near-identical match. LRV is estimated from each brand’s swatch, so order testers before committing.
