Which color is detected by the long-wavelength cone system?

Explanation:
Color vision relies on three types of cones, each tuned to a different part of the spectrum. The long-wavelength cones are most sensitive to the red end of the spectrum. When these cones are strongly stimulated, the brain interprets that pattern as red. The other cones handle other parts of color perception (blue with the short-wavelength cones, green with the middle-wavelength cones). Yellow isn’t detected by the long-wavelength system alone; it results from a combination of signals from long- and middle-wavelength cones. So, the color detected by the long-wavelength cone system is red.
