Can anyone tell me about monochrome papers that have a couloured base? I've recently bought some Guilleminot paper that seems to have been made as a brown. The attached photo shows the box, some lith prints and a Kodak grayscale.
Indeed!
Luminos made photo paper with base colors...(red, blue, green, etc.) back in the '70's...
It went well with shag carpet, bell-bottoms, and avocado-colored appliances.
