Mixing brick collections
The scattered flecks of dark brick are what catch your eye. There are plenty of ready-made collections, including a bunch of contrasting ones (Bavarian masonry). But in those ready-made collections, the mottled bricks or clinker tiles are mixed in roughly equal proportions. To get the effect shown in the photo, you need to take one base collection and mix in a small amount of contrasting brick from another. That gives you a unique look no one else has.
You can even lay individual figures out of brick. I once wrote about historical ornamental masonry — and there's a place for it in modern architecture too!
