Your blacks and whites are perfect, on my screen. I suspect that the green is pretty close to what I'm seeing here...remember every monitor shows color differently.
I'm knitting on 60 stitches and have past the heel on both socks - funny, to read that you are on the easy part of the sock. I consider the foot the tricky parts...toe shaping, gussets, heel, once I get past the foot, figure out what sort of ribbing I'm in the mood for then I think I'm on the easy part! Inches of mindless knitting in the round, nothing could be better.
