Transparent protein-based dyes for retouching black and white or color prints. These colors have been produced in Leipzig by the company Rohrer and Klingner since 1892.
The manufacturer played hard-to-get when we asked him if the colors sink invisibly into the emulsion, but in our own tests they work perfectly.
The dyes are available in various shades of black and gray, as well as color.
Each colour comes in a small glass bottle (12ml) with a practical dropper cap.
