The colours we see are interpreted by our brains based on signals from different types of cells in our eyes. So what if you could activate those cells without any ‘real’ colour existing at all?
Brand-new colour created by tricking human eyes with laser
Scientists have used laser light to activate a specific type of cone cell in the retina and create the perception of a colour that falls way outside the spectrum of what humans can normally see.
The closest match to the new colour is a kind of bluey-green – but the people in the experiment say that what they saw was far more intense and saturated.
