Skate parks are usually kept kinda drab on purpose, because chances are the skaters are going to jack the place up with their boards, and if anything the owners will let people paint all over their pools and walls.
I think the idea of letting patrons paint the place is a cool idea in an urban community sense but I think what artist Marco Mangione, aka Gue, has done with Darsena Popup Skatepark in Ravenna, Italy is even cooler.
Here's a bit more about this project:
gue’s abstract composition of colors, for the darsena popup skatepark, covers the entire park floor — adding a sensory dimension to the overall experience. the artist’s use of curvilinear lines mimic the moment of the skaters, and also highlight the features on the park’s surface — ‘offering an immediate ability to read volumes.’ this project continues gue’s experimentation with color as seen in the artist’s earlier work, a basketball court for carlo carra park in alessandria, italy.
