Is color blindness a point or frame-shift mutation?

Color blindness is typically caused by mutations in genes responsible for the production of photopigments in the cone cells of the retina. Most commonly, these mutations are point mutations, which affect a single nucleotide in the DNA sequence. However, some forms of color blindness can also arise from larger deletions or duplications of gene segments, which would be considered frame-shift mutations. Overall, point mutations are the primary cause of the more common types of color blindness.
