I wonder if we could try to see imaginary "supergreen" color by directly stimulating M cones. For this I suppose we'd need:
- Non-destructively scan specific human's retina to locate exact positions of M cone cells.
- Prepare a high-resolution image (on a retina-like display I guess), which would have light spots in some locations and dark in others, so that when the human we inspected looks at particular point of the image, these light spots were focused exactly on M cones.
- Track the eye movements and adjust the image so that S and L cones avoided significant exposure to prevent misperception.
Is anything of this hard to implement with current technology, given typical human retina properties (M cones density, their apparent color etc.)?
If this is totally possible, has such an experiment already been performed?
