Hi, I can't see enough of the Reddened Earth sample to tell at that distance, but I think you're on the right track. What I would do is find the color closest to your brick, and then use it on both the downspouts (as Chloe suggested) AND the garage doors. I always disguise downspouts on brick in this way, even if I don't use that color anywhere else on the house. Leave the garage surround (trim) white for contrast. Because your brick is highly variegated (contains several different colors), you won't be able to "match" it exactly. What you're looking for is a reddish brown that seems to best 'fade away' into the background of the brick. If you need to look at other paint decks, do it. The old Ben Moore "Classic" fan deck has a lot of muted red and orange colors that tend to sync up well with common brick tones. An ideal place to test your simulated brick color is on the downspout. Paint out a long section. If testing two colors, leave a foot or two of white space between them. The one that seems to disappear is your winner. In the future, when your budget allows for a full repaint, I'd probably replace the peachy sand color with something more taupe or greige, such as SW 7031 Mega Greige. At that point, you might choose to paint the doors greige as well, or if you're happy with the brick tone, they could remain. Downspouts should remain the brick tone -where they cross the brick- no matter what.

Here’s a picture of the whole front. Ignore the trash pile awaiting its weekly pickup. Oh, also, that one beige board will eventually be trim color. It had to be replaced and the new board hasn’t been painted yet.

Snap a photo on a sunny day then use the Sherwin Williams ColorSnap app to play with the colors. I would select a tone slightly darker than your mortar for the garage door and a color slightly darker than your darkest brick for the front door. I would then on the garage door install magnetic faux hinges and windows; this will add detail to the door, like the below house. I know they can be found on Amazon, not sure where else. Before: After:

I would not paint the brick. The brick is what makes your house stand out and I do not like grays or blues with brick.Do the siding the same as the window trim and you could do the garage door the same . Then go to work with landscaping that will up the MCM look much more than paunting the brick.
