Unlocking New Colors: Laser Stimulation of Cone Cells
2025-07-21
A study used laser pulses to selectively stimulate cone cells in the retina, claiming to allow people to see unprecedented colors. While the study lacks detailed subject reports, an optical illusion animation seems to produce a similar effect. The animation saturates red cones with a red circle, highlighting green cone activity and producing an intense blue-green. However, due to overlapping cone spectra and screen display limitations, whether this approach reveals colors beyond the normal human color gamut remains questionable.
