I'd me amazed if they weren't. The beauty of piezo (or straight MIS) is that all the ink is pure black. No two pigments have the same fading properties, so it would be amazing in blue faded at the same rate as black. Most likely, it will fade faster because carbon black is the most stable pigment known. If this happens quickly it could be a major problem for the MIS VM inkset for archival applications. I'm not sure how Cone is achieving the Selenium Toned set...but the problem could be the same.
