Marine Blue is a deep blue-green from Little Greene. As a premium paint, it’s a popular colour to seek out close matches and value-brand alternatives to.
Sailor's Coat by Johnstone's is the closest match from any other brand (close) — though it’s slightly warmer and noticeably softer. It’s also the best-value tier of the close matches — unusual, as the nearest match and the best-value one usually differ.
