According to the trichromatic theory, the perception of color is based on the relative activation of three types of cones in the retina: red, green, and blue. In the case of distinguishing between red and orange, the two colors would produce different ratios of responses by the cones, with more red wavelengths stimulating the red cones and fewer stimulating the green cones, while more orange wavelengths would stimulate both the red and green cones to a similar degree. Therefore, the brain uses the relative responses of the red and green cones to determine whether the color is more red or more orange.
