- Human eyes sense color through three types of cone cells (S, M, L) with overlapping sensitivity to light wavelengths.
- Laser stimulation of individual cone cells can create new, highly saturated colors not normally experienced.
- An optical illusion involving a shrinking red circle on a blue-green background can induce hallucination of intense blue-green colors by desensitizing L cones.
- The human color gamut in LMS colorspace represents all possible color experiences, limited by cone cell sensitivity and overlapping spectra.
- Standard RGB (sRGB) colorspace used in screens cannot fully represent the human color gamut due to technological limitations.
- Optical illusions may not fully escape the natural human color gamut due to screen limitations and cone saturation effects.
- A customizable tool allows users to create and explore similar optical illusions with various colors and parameters.
