I've been wanting to do some experimenting with repeating shapes. They can look really cool when used in designs. So here's a set of triangles. The first one is just with a stroke — mint green is trendy and it goes with pink. The second is with different opacities. I don't love it. I wish the stroke stayed 100% while the inside changed. Maybe you can do that but I don't know how. It would be worth trying over a photo. The third is different shades. I like it.
