With the popularity of Archival inks, I thought this was a good word to give meaning to.
Metamerism is phenomenon produced when using Pigment based inks only. Due to the nature of all pigment based inks, unlike dye based inks, lighting conditions can affect the appearance of colors in the printed output. For example a sepia tone may appear a golden tone under incandescent lighting but will appear greenish under normal daylight. Adding more red to compensate for the greenish appearance in daylight will actually cause a burnt reddish tone under incandescent light. Even flourescent lighting will affect the way our eyes perceive the colors.
Some colors will be affected more so than others but I think yellows especially when sepia toning is the worst. I've found this to be a noticable difference when doing a subtle sepia tone vs. the bright vivid colors of modern photography so I would say less saturation makes it more pronounced. (Personal opinion here)
This should be taken into account when printing an image. If that image will probably be viewed under artificial lighting vs daylight you will want to compensate for this.
