Why wear blue when boating?

Wearing blue on a boat isn’t something that has been ‘en vogue’ the last few decades or so. When we tried to trace the origin of nautical clothing, the earliest descriptions we found were about Roman ships. They used light blue sails for their boats and the people aboard wore matching colours. This wasn’t because they’d found a big barrel of blue dye and were at a loss what to do with it. The blue sails and outfits were meant to have the same colour as the sea, so the Romans would blend in with the environment and have the advantage during attacks at sea.
