The graffiti project for the GaleRio was piloted on the Del Castilho station where a group, led by Mighuel Afa, created an abstract, colorful piece, in pop art style.

The wall separating the stations of Colégio and Coelho Neto will be graphitized by 70 artists, led by Rafo Castro, Anarki, Fael, Bands, David, Baltar, Brutto and Denne.
