A family has four children, two girls and two boys. One girl and one boy are color-blind. Are their parents color-blind? How can you tell?

Believe it or not im colorblind i am male my chromosones are X and Y the Colorblind trait uses the X chromosones so imagine x is a fighter and fights colorblindness the colorblindness wins you get colorblind but since females have 2 xs their less likely to aquire the trait Twos better than one!
