The erythrolabe cone is responsible for seeing which color?

Explanation:
Color vision relies on three cone types in the retina, each tuned to different parts of the spectrum. The erythrolabe is the long-wavelength–sensitive cone, best stimulated by red light. Its photopigment peaks in the long-wavelength range, so when red light activates it, the brain interprets that input as red. The other two cones are responsible for green and blue perception, respectively. Yellow, on the other hand, is usually perceived from a mix of signals (primarily red and green), not from the erythrolabe alone.
