Vanadium alone produces deep-yellow to orange colored images, but when combined with an iron salt, such as ferric oxalate, the yellow image of the vanadium ferrocyanide and the flue image of the ferri-ferrocyanide form a brilliant green. This is a most unusual and difficult to use toner. It is the only toner that produces a true, bright green. When it works, it looks beautiful. Unfortunately, a great deal of trail and error is required to get it to work.
