How to test GUI for color blind person?

Question

Is there a way to test if a GUI is usable for color blind person?

I know that it has many degrees and I guess that's why simply doing a screenshot in black & white is not the best way to test the usability of a GUI for a color blind person. What is the best way or best tool to do it?
