[help] Question about human evolution

Is 25-50 generations sufficient elapsed time for a human population under significant selection pressure to exhibit significant phenotypical variation?

I'm assuming something like a lost colony scenario, and/or multigenerational space farers. I'm also not looking for 10 foot tall green men or anything like that, but more along the lines of meaningful changes in height, build, coloration, body mass, musculature etc. such that current extreme expressions might become more common or even typical.
