Mountbatten Pink, also called Plymouth Pink, is a navy blue camouflage color resembling grayish purple. It was first used by Lord Mountbatten of the British Royal Navy during World War II. After noticing a Union-Castle Line ship with a similar camouflage color that faded from the eye, he applied the paint to his own ships, believing the color would make his ships difficult to see at dawn and dusk. While the color has seen anecdotal success, experts felt it was at best on par with neutral grays and at worst would make vessels of that color more eye-catching.
