Colour blindness is actually a recessive gene carried on the X chromosome. The only way your daughter could be colour blind is if she got the gene for it from you and your DH. But this would mean (as men only have one X chromosome) that your husband would also be colour blind. If he's not, then she's just finding colours a bit tricky.

Rarely girls can inherit only one affected X chrom and still present with colourblindness. As women have 2 x chromosomes, one of them is randomly inactivated in each cell. If the non-affected chrom was turned off in all the eye cells (or whichever cellls dictate colour blindness) then a girl child could still be colour blind.
