On some Final Fridays there’s too much going on to recommend just one show — so how about three within walking distance? First up, Primaries at Yes in Over-the-Rhine celebrates the work of more than 20 international artists and designers who examine the chromatic possibilities inherent in humble heroes red, yellow and blue.The Revolution Says to further the painter’s exploration of contemporary institutional spaces and the emotional responses they evoke. Two blocks east, the Art Academy of Cincinnati hosts Sub-Surfaced, a senior thesis exhibition featuring works by Scott Bunge, Tyler Hilton, Julio Labra, Justin Mangan, Vladimir Plitsyn and Chris Schimmel. While each of these young artists maintains a unique approach to craft, they are united by a focus on surface, both as a material property and metaphor. Primaries, 6-10 p.m., Yes, 1417 Main St.; The Revolution Says, 6-9 p.m., Clay Street Press, 1312 Clay St.; Sub-Surfaced, 5-8 p.m., The Art Academy of Cincinnati, 1212 Jackson St.
