The finding, published in the journal Science Advances on Friday, comes from a bold experiment where researchers used laser pulses to target specific cells in the eyes of participants.So how did they see this ‘new’ colour? Human eyes detect colour using three types of cone cells — L (long), M (medium), and S (short) — which are sensitive to red, green, and blue light respectively.
