[H]ow does the light sensitive graph look for someone whose vision is red and green deficient?
In this chart, which shows sensitivity to light by the four different types of photoreceptors we have: rods (for scotopic vision), and three kinds of cones (for photopic vision) ? long wavelength (red), medium wavelength (green), and short wavelength (blue). Note that the x-axis in this chart is reversed from those above. Blue cones have their peak sensitivity in indigo; green cones in green; and, red cones in yellow (greenish yellow?). Rods are most sensitive to cyan or blueish green.
In the most common form of color blindness, red-green, the green cone sensitivity is shifted in the direction of the red. How much, I don't know, and it may vary, but it's enough to preclude an ability to discern the difference in the two colors. The peak sensitivities of normal green and red cones are close to the integrated photopic peak at about 550 nm. Thus, I'm guessing the red-green colorblind eye will still be fairly sensitive to green, but likely peaks in the yellow.
