Here we are with Roy’s toned in tannic acid. The print was washed in running water and was set aside to dry. It was then immersed in a 1 percent solution of hydrochloric acid followed by a quick bath in tannic acid. This changed the Prussian blue to charcoal, gray, and rose.

Here we are with Roy’s Cafe in blue. I worked out a couple of kinks yesterday enabling me to arrive at a decent test print today. I applied a curve to the digital negative and used no color fill. Exposure was 5 minutes and the print was developed in plain running water.
