Yeah, colorblindness (or red-green colorblindness, anyway) is a
sex-linked recessive trait. So it only shows up on the X chromosome,
meaning if you're female, your two Xes mean they've both gotta have it
for it to manifest, but if you're male you've only got one X, and if
it has the color-blind bit, it manifests.
I just looked that up because I couldn't quite remember how it worked
from high school biology :-)
