Go on to a site like Sherwin Williams and load your photo above into the ColorSnap app. Click on the "Explore Color" menu and then select "match a photo". You can then pinpoint all the colors in your brick and find some options from there. pS: It looks to me like greige would be a good option worth considering.

I just came across this picture from Ford Cottage in Norfolk. The brick may be a slightly different hue, but I love the use of cream and blue. You could substitute the sage green for the blues.

Sage green seems like it would work if you're going for a color. It would help to see the rest of the house. Are there any other colors on or around your home that you could draw from? Think landscaping, shutters, details, etc.

Are you painting the exterior or working on an interior space?

For the exterior, if you can eliminate all white (some folks have fixed white windows) in favor of off whites and creams, that would be a good first step. A terracotta colored front door would be wonderful with this brick, and a great trim color might be found in the olive drab warm grays . . like bm equestrian gray.

You have earth tones - cream to brown, and terracotta / red-orange accents in the brick. Inside you can successfully riff on yellow based beiges, camels . . ..autumn colors / pumpkin/ eggplant / a range of khaki greens. Olive drab greens are going to be a tad more successful than sage .. look at bm tate olive, bm Spanish olive ..

Sage green makes no sense. Stick with the colors that are in the brick. I see chocolate browns, gold, black and cream.
