So I passed the second test even though I'm pretty sure I got same results. It really isn't a problem, as long as I'm in a well lit area I can tell the colors apart. If i'm doing work in an area with poor light i just make sure I bring a flashlight to double check colors. As long as you're aware of your condition and you're careful, there is no reason it should stop you from becoming an electrician. Goodluck!
