Color films contain much less silver than BW films. Developing a color film in a BW developer will result in thin and flat negatives. Not really worth the effort.

I keep fantasizing this is the last roll of Kodachrome left in the world. But I am sure there are others who still have KC hidden in the deep recesses of a fridge somewhere. Be that as it may, I read in passing, on Apug, I think, that KC can be developed in B+W chemistry. Any truth to the idea, and if so, what would be the best brew? Last week, I was also given 4 4x5 sheet film holders loaded with Porta 100. I'm not into colour but B+W. Anyway, can the Portra also be done in B+W chemistry? By the way, the holders were accompanied by a Graphic View I in its case and an Ektar 203/7.7 lens mounted on the lens board.
