Human vision relies on three main cone photoreceptors: • Short-wavelength cones (S-cones), which respond most strongly to blue light. • Medium-wavelength cones (M-cones), which respond to green light. • Long-wavelength cones (L-cones), which respond to red light. The visual system is particularly sensitive to wavelengths around the
