[Gimp-user] Converting a color into another color.

[Pere Pujal i Carabantes]

Hi all!

I have two photos of the same subject: one blured taken withouth flash,
the other taken with flash is clean but has a reflected color from the
background mixed with the subject colors.

My idea is to translate the colors on the clean photo to the colors on
the blured one.

How do you suggest I can handle this?
So far I've tryed colortoalpha, that does some sort of color conversion,
but I am unable to find the right color to start with.

Any hints will be appreciated.
Thanks
Pere
