Even if you have decided on “brick red” still go to the paint store and get chips of several different red paints and compare them to your brick. Your birck looks to have a lot of yellow in it, so the red you use should have a trace of orange in its mix rather than a trace of blue in it.
It also looks as though (as is common these days in Texas) you have bricks of several different colors so you could use variations of those different bricks as your base color, and then choose either a darker or lighter hue for the trim and the door. That could lead you to yellows or even oranges.
You also could pick an opposite on the color wheel . That is why green goes well with red, and blue with yellow.
And sometimes you can pick a color that is next to one of your brick colors. If you do that you might be able to use one color for the trim and a second for the doors. If you want to get fancy you could make the garage doors one of the colors with square overlays of the other.
