Seniors at a southern Iowa high school have left behind a colorful mark on campus grounds by spray painting onto concrete their names and other sentimental details, such as athletic jersey numbers.

The Oskaloosa Herald reports that the Oskaloosa High School’s Class of 2016 channeled their inner artists on Tuesday, covering the Indian Trail that leads up to the school’s parking lot with spray paint.

Student Council Advisor Kim Gile says students in years past had painted their names on a street, but the tradition had to be moved to the Indian Trail due to safety concerns.

Senior Anna Kain said she and her best friends had planned their color scheme beforehand and went as a group to go pick up supplies at a store.
