Anyone know what this grass is?

The more emerald colored grass is centipede that I patched in last year. I'm now wondering what the more faded grass is as I always thought it was centipede. It has runners like centipede. This grass was in this yard when we bought the house n 1992. The grass may be from when the house was built in '54. We have a service fertilize.
q anyone know what this grass is, gardening, landscape
