Have you ever noticed that some colors feel brighter or easier to see, even at the same brightness level? That is not random. It comes from how your retina is built. 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
