Caffenol Strong and a little color

I have a secret faith, I believe that I will someday be capable of developing C41 films without the special substance CD4 a paraphenilenediamine derivative present in C41 developers. But until this day comes, I go on experimenting. Some people claim to develop color with hair dye but I never saw acceptable results of this. I had luck too sometimes but never was able to reproduce the result.

The work solution of Caffenol Strong, which is almost only soda, I use to discard. But the last two times I decided to keep the work solution and give it a second chance.

Last weekend I drove some 100 km around my town and took some pictures with a dsposable camera, while driving. The weather was clowdy and rainy with the Sun showing from time to time. It was nice to drive under this weather conditions.

Once at home, I decided to develope the film in Caffenol Strong to which I added 10ml of a 1/2 liter solution of hair dye in water. A 60ml tube dissolved in water. If no color would be developed, at least I would have a B&W negative. In fact we can't speak yet of color process but some pictures were nice to see when scanned as color negatives.

The pics above suggested me to colorize them with blue, specially the number 1 that resulted a little blueish. And the result is to be seen bellow:

Example 1 - Blue

Example 2 - Blue

Example 3 - Blue

Example 4 - Blue

OK! I didn't get color yet, but my faith is not touched, I will continue trying and trying.
