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

This dataset contains:

* *LMS* values for each color match, and for averages of color matches.
* Individual responses for each alternative forced-choice (AFC) trial, and aggregate accuracies.
* Code for reproducing the data plots presented in the manuscript.

Also included are the data needed to compute the *LMS* values from the subject's raw responses during color matching trials.

* Raw 0–255 RGB bitlevels chosen by subjects.
* Raw intensities and center wavelengths chosen by subjects in matches which use the tunable wavelength source.
* Spectral power distributions for the RGB projector primaries.
* Look-up table used to convert 0–255 RGB bitlevels to linear intensities for each projector primary.
* Spectral power distributions for the subjects' chosen tunable-wavelength source settings.
