Rhodopsin is found in rod cells and is responsible for vision in dim light. It is not sensitive to many wavelengths, but rather is mainly sensitive to blue-green light. Cones, on the other hand, are responsible for color vision and are sensitive to multiple wavelengths of light. Rhodopsin defects are also associated with certain forms of colorblindness, but not necessarily red-green color blindness specifically.
