[Gimp-user] Undo the last actions of a recently opened file

[Johnny Rosenberg <gurus knugum gmail com>]

I create an image from a few pictures. I make the whole thing black and
white and I add some more effects.
I save the image, it ends up as a XCF file. Good, that's what I want.
Next day I want to use the same image but want to get the colours back.
However, it seems like my undo history is gone. I thought that saving as
XCF would mean that I could continue my work later, undoing,
redoing,manipulating etc.

So can I do this at all? If so, how?
