Ott lights show truer color....like holding something up to a sunny window. They make a small, portable one that I carry in my purse for fabric shopping . It, of course, will not change the fact that you are colorblind but may help a little with matching fabrics. Over 90% of colorblind people are male. Females with colorblind fathers usually pass it on to their sons (my father was not as severely colorblind as my son is though) but being a colorblind female is not unheard of. I'm sorry it gives you trouble. You need to quilt what makes YOU happy. Don't worry about what others say "goes". Some people can be cruelly critical.
