I have a brand new System76 machine, which shipped with 15.04 and Unity. I'm getting it set up and somewhere along the line I managed to turn my launcher green. I am still using the "ambiance" theme, but suddenly the launcher is this cloying shade of turquoise and I absolutely loathe it.
The problem is that I can't figure out when this happened. At some point I installed CCSM and then realized I didn't want it, and removed it, but I'm not sure either was what did it. Either way ... how do I change it back to boring old ambiance slate?
