Scientists say they have discovered a new colour only ever seen by five people in the world - called ‘olo’.

The colour, said to be a saturated shade of blue-green, cannot be seen by the naked eye without the help of stimulation by laser, which scientists claim can open people to see beyond the normal gamut of colour perception.
