For a Genetic Disorder project for a school I need to understand what causes Color Blindness and by that I'm talking about the DNA and chromosomes.
Could someone please explain what happens to the chromosomes when someone is born with Color Blindness and why it happens more to men than women?

Color blindness, more appropriately called color vision deficiency, is a condition in which certain colors cannot be distinguished, and is most commonly due to an inherited condition. Severity of the color deficiency varies.
Or
Color blindness is due to a recessive allele present on the X chromosome, but not on the Y. This explains why there is a significantly larger amount of its incidence in males (XY) versus females (XX). Males only need to carry one allele for the condition, whereas it must be present on both X chromosomes in females in order for it to show...
Treatment for color blindness
There is no treatment for this disorder But people with this disorder can probably get therapy for this...!!

If a woman's father is colourblind, then she will have the capacity to be a provider, because the in reality way for her to be lady is to inherit X chromosomes from both mothers and fathers, and the only from her father could be faulty. She has conventional sight, subsequently she is a provider and must have one faulty X chromosome. If she marries a colourblind guy, who could actually have a faulty X chromosome, then in the experience that they have got a woman, there's a a million/2 possibility of the female getting her faulty X chromosome alongside with the daddy's faulty X, and could be colourblind. further, a a million/2 possibility of having a regular maternal X chromosome and the faulty paternal X chromosome and being a provider. With sons, there's a a million/2 possibility of having the faulty maternal X chromosome, and being colourblind and a million/2 of having a regular maternal X chromosome and being unaffected. The Y chromosome from the daddy received't influence the son's colourblindness. So, a million/2 possibility. Do the punnett sq., yet that's your answer. .

Look up sex linked traits or sex linkage in your biology textbook. The defected gene is located on the X chromosome.
A full explanation would require many paragraphs and Punnett squares.
