Unfortunately, most people who are color blind cannot distinguish green from red. I'm not sure what such people actually see, though, since I'm not color blind.
Using the light green over the dark green and orange over the red are generally poor choices for color blind people too - in both deuteranopia and protanopia lighter reds and greens can approach white depending on the severity of the condition, and be completely unreadable. Darker reds and greens, whilst impossible to differentiate for sufferers, are at least readable.
Red and blue are commonly used as contrasting colors which are differentiable for both deuteranopia and protanopia, although the former will see the red as a dark/dirty yellow and the latter will see it as a brown. Tritanopia sufferers generally have no problems distinguishing red and green, although the green will appear blue to them.
The best solution from this point of view would be changing the colors back to the dark green and red, and having a checkbox somewhere in your profile settings to switch to dark blue and red if you desired.
