The speed of light and the color of light are related. If the speed of light has increased, would the old light from galaxies long ago and far away appear to be redshifted?

I actually sat down to do some calculations trying to figure that out assuming that light had changed speeds over history, i.e., c = c(t). I got up after my head started hurting. Ever since I went to an astronomy lecture about the red shift as a child, I have wondered whether there was another explanation for it and maybe this is it.

I have always thought there was another explanation. Makes my head hurt, too.
