No, that was not my intention. I had to figure it out myself. Today's goal is to empty the stand of the 60 and start setting up the 55 gallon holding tank. Now that I have an idea of what color to paint the wall. I may go look for and purchase the paint. I need to paint an area that's roughly 12x12. It's going to be the only wall that gets painted that color. How much paint do you think I'll need? I'm covering a currently white wall with a somewhere between Olive and Militant green color. Any painters? Do I really need to prime?
I am not a pro painter by any means and I hate painting, but if the wall is already painted the drywall is "sealed", and since you are using a darker color over white, just apply 2 coats to be safe and give it a nice even look and you will be good.
If you buy a good quality paint and a decent roller One gallon will be enough for a 12x12 wall

Dont forget to do your "cutting in" before you roll, the edges and allong the other wall this is where you use a angle cut brush to paint the wall that is getting painted
