I took a walk on campus on a sunny day in August and took the following images.
blue mark on a parking lot
white marking with a cracking on a parking lot
white line marks with x mark in red on a parking lot
T mark in orange and other makrs in pink with shadow
tree shadow and rush showing up on the road surface; can I call them marks?
the shadow of a rail crossing sign
After crossing the railway, seeing the shadow on the surface of the white structure
white mark for fixing this bolt, probably
I enjoyed a small walk on campus to find marking on the ground. I do not mean I always looking down when walking though—.
