The gene for colorblindness is on the X-chromosome. Since males only have one X-chromosome, they can't have two different alleles for the trait. They either have normal color vision or colorblindness.
(Unless they have an extra chromosome and are XXY). Then they have more problems than colorblindness.

women's chromomsomes are XX men's are XY they only have one Xchromosome. whereas women have two which makes it more likely for women to get colorblindness and not men.
