Not the OP, but I'm also R/G color blind and I don't believe I'd have any issues with those extreme versions of R and G. My issues happen with lighter shades.
For instance, 00AA00 and 00BB00 are very hard for me. 00CC00 is about when I start feeling confident I could recognize it as green, but it's be harder if the surface area was fairly small (for example text). On the red side, the recognition issues also extend to about CC0000.
