Shrimp give new perspective on colour vision

Colour blindness tests on shrimp have quashed assumptions that more complex eyes mean better colour vision.

Scientists found mantis shrimps, which have 12 colour receptors in their eyes, had worse colour vision than humans, who only have three colour receptors.

Animal brains usually encode colour through the relative stimulation of their colour channels, but this research suggests shrimp brains do not do this.

The findings could provide bio-inspiration to develop new technology to better interpret colour in cameras.
