Thanks for the link, Bruce! The aesthetics side of it is interesting. I also find it interesting that in the early days of photography the color/tone was largely determined by the process. Cyanotypes were blue, but then they could be toned (although often with adverse affects on their archival qualities). Other processes were various shades of brown. There were always some who looked for ways to change the tone after the print was made with various methods from chemicals to teas. Looking through an old Kodak formulas guide, I was surprised to learn of Kodak T-9, a Uranium Toner. http://www.jackspcs.com/toner.htm I would imagine that this was one justification for Kodak operating a nuclear reactor in Rochester (unknown to the general population) for many decades. http://www.democratandchronicle.com/article/20120511/NEWS01/305120021/Kodak-Park-nuclear-reactor
Color printing of when inkjet printing digital B&W negatives on transparency material (for contact printing) - although for different reasons. Rather than making the negative with black/grey one prints it as orange, since the orange does a better job of blocking UV rays than even black/grey does. I've seen CMKY values of 0,71,71,0 suggested (for example). It varies a bit depending on your printer and inks used.
