If you develop an RA4 color paper in black and white chemistry, you will get a low black-and-white image, but it will appear very bright and with very low contrast.
Color paper also contains a small amount of silver, which will react in the same way as black and white paper money when developed in black and white chemicals, but not enough to create dense, dense blacks. . The silver colored paper is only intended to react with color couplers to form dyes during development and is, if treated in color chemistry, removed by paper washing during the course of the process. bleaching step.
