Anna, you are truly unique. Color blindness is rare among females. Granted, it's rare among males as well, but much more so for gals.
The most common form, Deuteranomaly (a type of Red-Green color blindness) effects approximately 6% of males but less than 0.4% of females. My father had a severe case of Red-Green color blindness. He always joked that that was why he was such a good shot. Because, when deer hunting, he had to make the first shot the kill shot because he wouldn't have have been able to follow a blood trail, unless of course it had been snowing, then who cared what color the blood looked like. Of course, if it were snowing, I'd follow the tracks ;-)
Note that my interest in the issues of color blindness was not really because my father's situation, but rather it came about when I was the project manager for a major update in our software user interface and we needed to make sure that it was usable by people who were color blind, so I did a bunch of research on the topic. This included finding a set of color charts that compared what a color blind person would see versus someone who was not color blind. So we had to make sure that when we used colors to indicate something in a menu or say highlight a choice, that we avoided using colors that a color blind person would find hard to distinguish. Obviously you would avoid changing something from Red to Green, or vice versa, to indicate a state change or an option being set. And it could also be an issue when people used a lot of colors for components in their CAD models and while we did offer photo realistic rendering, that usually required a lot of computer power (or at least it did for a long time before the 'Gamers' got the hardware people to produce miracles in silicon), so most people stuck to a form of the RGB color palette. In our case, we used one based a cube made up of six layers, each layer consisting of six x six colors, for a total of 216 colors. Black and White occupying opposing corners, and the remaining six corners being assigned the primary and secondary RGB colors of Red, Green, Blue, Yellow, Cyan and Magenta, with all the variations in between. In fact, I even wrote a program that our customers could run on their models so as to temporarily show them what that model would look like to a color blind person, in case that was something they needed to concern themselves with.
