“Wearing a light blue wetsuit that matches the colour of the sea will make you less likely to become the victim of a shark attack, according to researchers.
Sharks are completely colour blind and only see things clearly if they are mostly light or dark, scientists have claimed.”according to the Daily Mail.

This does not make a lot of sense – if sharks are colour blind then it wouldn’t matter what colour you wear. But later in the article the point is put better by Professor Nathan Hart, from the University of Western Australia: ‘It’s the high contrast against the water rather than the colour itself which is probably attractive to sharks. So you should wear perhaps more muted colours or colours that match the background in the water better.’

Apparently sharks really are monochromats – so colour blind in the popular understanding of the word – and so it’s really a case of matching the yoru swim suit with the lightness or brightness of the surrounding water. Don’t wear a very bright or a very dark swim suit, in short. Maybe this can lead to better designed swimwear!
