I have a grid set up with a brick texture, and I want to have only the green mortar showing up, so I tried setting the alpha for color 1 and color 2 to 0, but the bricks are still opaque. How can I fix this? Should I even be using a brick texture for this?

"Fac" output it is alpha value. Connect it to Alpha input
Note, that if you are using EEVEE, you should also select transparency mode (Blend mode) in material settings:
