are made with dyed printing papers
produced by commercial manufacturers. A single overall colour underlies the image and is most apparent in the highlights and mid-tones. From the 1870s albumen
printing papers were available in pale pink or blue and from the 1890s gelatin silver
printing-out papers in pale mauve or pink were available. There were other kinds of tinted papers as well. Over time such colouration often becomes very faded.
