Gradient, yes, this thread is quite similar to the other but I see it as different.  I refer here to an entire image with a color cast such as the blue I mentioned.  With a film image, and scanned at that, there is no raw file to work with.

Maybe I should have called the thread " Recovering Photos Miscolored in Process" or something similar.     Then again, if not worth posting about, responses will not be here. I can live with that, too.     Thanks.        TomDart.
