Scientists claim to have discovered ‘new colour’ no one has seen before

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.

Researchers developed the Oz Vision System technique, named in homage to the green-tinted glasses that people in the Emerald City wear in the ‘Wizard of Oz’, to reveal the new colour in a study, published in the journal Science Advances.

It found when Oz laser signals are intentionally “jittered” by just a few microns (one millionth of a metre) subjects perceive the stimulating laser’s natural colour.
