Unfortunately once you've converted an image to grayscale and saved it,
the color information is irretrievably lost. You can try to color the
picture, but that's more like painting it, not restoring it. If you have
another picture of the same scene taken shortly before or after the one
you're trying to restore, perhaps you can sample the colors in the
former to hand-paint the latter. But like I just said, this is not
really restoration.
When you edit a picture, it is good practice to leave the original
untouched and only work on a copy.
