This morning, while I was doing my DFW Ambassador thing at Gate A-9, I looked to the north to watch the aircraft that were taxiing on Zulu and Yankee (believe those are the two East to West cross taxiways that head from the East to West side of the airport), and I observed what appeared to be an EMB 120 with the oddest color scheme (Yellow in the middle, with Purple on the top and bottom) and what I thought was ?CA on the tail. Can someone help me identify this commuter airline? Richard Whitenight
