Orange and green can even work outside. Here the orange door is drawn into the yard by the light orange tiles. The green is provided by the natural landscaping. However, I think that they trim of the house could also be green here for a great cohesive exterior look.
Circular, sunburst pattern on a brick pattern. I did a circular flower pattern like that but added a truncating circle around the first 3 feet. Then we found free bricks on Craigslist and I don't know what to do with the different sizes. This might be it.
I like the radiant design of the brick pavers, and that the ground cover aggressively covers whatever the foot traffic allows. Pretty cool shade pattern overlaying everything. Probably just the right amount of light for this kind of ground cover.
