Her male children
will be colorblind because all of her male children will have one of her x's with the colorblindness gene and a y from the dad that cannot cancel out the colorblindness gene on her x.
If she has children with a man who is not colorblind than her daughters will carry the gene, but not be colorblind themselves since they'll have a normal x from their dad to cancel out their mom's x with the colorblindness gene.
If she has children with a man who is colorblind, then her daughters will be colorblind also.
This is why colorblindness is much more common in men than in women.
