Pathécolor

Pathécolor was a labor-intensive, mechanical stenciling process used to add color to black-and-white films by tracing and cutting specific areas for each hue onto a blank film strip. These stencils were then placed over the final print in a machine, where aniline dyes were applied through the cutouts via velvet rollers or ribbons. This, and similar, methods allowed for vibrant, multi-colored images with sharp, well-defined edges.
