If you haven't heard anything yet; I wouldn't worry about it. It took about 2-4 weeks to have my paperwork stamped, but if they didn't find anything at WPAFB then they won't find anything as it gets signed off.
As far as the color test goes the laptop is a bit harder for me, and I have never failed a color test in my life. The laptop can be hard to see, but if you do end up failing that then there are two other tests they put you through. The first is the standard book test if you pass that then they will give you another test where you have to match colors (a sphere split into two halves). I know this because a buddy of mine was color blind and ended up passing the book test (mainly because he knew what he was looking for), during his appointment at WPAFB he failed the laptop test and then later failed the sphere test. This is the main reason they changed the test, you can study for the book, where as you can't study for the laptop test.
