There are few apps to help you with your color blindness.
I use ColorCompass .
It's very effective app, that gives you names of colors in real time. The names are simple terms such as blue, green, red... It helps me a lot with powerpoint presentations.
It's a paid app, but quite cheap.

If you want something free, you can try ColorQuest. But it's not so much user friendly (slow, does not stay on top).
