Which photopigment is found in M-cones?

Explanation:
Green-tuned cones use chlorolabe, the pigment that makes M-cones sensitive to medium wavelengths. Cones come in three types, each with its own photopigment: erythrolabe for red (L-cones), chlorolabe for green (M-cones), and cyanolabe for blue (S-cones). Rhodopsin is the rod pigment used for vision in dim light, not for cones. Chlorolabe peaks around 530 nm, matching the green light that M-cones are most responsive to, so it’s the pigment found in M-cones.
