Sometimes you have to Exit and restart the IDE in order for new libraries to be recognized.

You always have to restart the IDE if you added a new library manual (not via add zip).
But some thoughs:
Something turning orange or not tells you absolutely nothing. That's only very simple code highlighting done based in the keyword file in each library. But besides from that word being on a keyword list it tells you nothing about it working or not. Try
Serial.digitalWrite();
[/code]
For fun. Turns orange but is nowhere correct or compiling. A lot of libraries don't come with a keyword file because of that.
If you downloaded it from GitHub, rename the directory so it does not contain "-master".
And the correct folder to extract it is the libraries folder inside your sketchbook (default "c:\Users[user]\Documents\Arduino"). NOT the libraries folder inside the Arduino IDE install directory (the one with "Bridge" and "Servo" in it).
