Color Blind?

I just wanted to know who else is color blind? I posted here because I want to relate it to seeing ferraris. I find it really frustrating when I can't tell the colors of the car. It really really sucks. Some of the light blues look the same to me. Some of the dark blues looks the same to me as well. It just really pisses me off when I see a ferrari, and I can't even tell someone who color it was.
