Once that is achieved, color and contrast can be easily controlled. One of the advantages of the Ziatype system is the ability to get a wide range of colors by simply adding various compounds to the emulsion. The Ziatype is a work in progress and has a multitude of variables. Workers are encouraged to experiment. A lithium palladium print that has been exposed and allowed to sit without washing and clearing will progressively turn brown.
Colors vary with paper, humidity level and amount replaced.
As more is replaced, the contrast increases. Variations in color can be obtained by mixing brown additives with the gold chloride. The possibilities are endless and have not all been tested. Individual printers can develop unique combinations to suit their own needs and desires. The Ziatype was named for the ancient New Mexico Anasazi pueblo people's symbol for the sun.
