It's hard to choose. You can get paint tinted to both those though and try them out and see what you think, we did exactly that recently when trying to choose a new roller door for our place, we ended up with night sky. Our brick is a lot darker than yours though.

The darker the better, black looks fabulous with cream brick , really adds a wow factor.

I think night sky would look fabulous. I would also paint the full garage/new roller door, in night sky as well. The dark colour will make the greenery stand out. Your home is going to look wonderful.

Like your house style. All in Night Sky.

Those photos really help to visualise it. Thanks everyone , I will defintetly go with Night sky now.

I might paint a small are of the garage night sky and see how I like it. A lot of that greenary between garage and front door is gone now.
