Why is my board outlined in yellow?

There are two conditions that cause your board to be outlined in yellow:

1. A module that requires a connection is not yet satisfied, and
2. And another module on the board can satisfy the requirement of the yellow module. 

To turn the board green, click on each yellow-shaded module, check all the flags and see which ones are yellow, click on it, and make a compatible connection.
