Data from: Novel color via stimulation of individual photoreceptors at population scale

We introduce a new principle, Oz, for displaying color imagery: directly
controlling the human eye’s photoreceptor activity via cell-by-cell light
delivery. Theoretically, novel colors are possible through bypassing the
constraints set by the cone spectral sensitivities and activating M cone
cells exclusively. In practice, we confirm a partial expansion of
colorspace towards that theoretical ideal. Attempting to activate M cones
exclusively is shown to elicit a novel color beyond the natural human
gamut, formally measured with color matching by human subjects. They
describe the color as blue-green of unprecedented saturation. Further
experiments show that subjects perceive Oz colors in image and video form.
The prototype targets laser microdoses to thousands of spectrally
classified cones under fixational eye motion. These results are
proof-of-principle for programmable control over individual photoreceptors
at population scale.
