Sex linked
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.

Colorblindness is characterized by not being able to tell apart two colors when they are the same value. Colorblindness is an x-linked trait, so it is much more common in males than females.
No, the term "red-green colorblindness" means that you cannot tell the difference between red and green. There are several different types of colorblindness; red-green colorblindness is the most common kind. For example, another kind is blue-yellow colorblindness, where a person cannot tell the difference between blue and yellow. All types of colorblindness are much more common in men.
