It's certainly true that red-green colour blindness (by far the most common type) is far more common amongst men than women, affecting around 8% of men and only about 0.5% of women. The reason for this is that it's carried by the X-chromosome, of which men have only 1, but women 2, and a woman will only suffer from the condition if both her X-chromosomes have the genetic defect.
