The hue is 1109, the same as the old evil mage cloth, which is also the same as Shadow Dancer Black Tokuno Pigment. The cloth was also available briefly from a bug with Thrasher following the Mondains Legacy release, making the cloth itself less valuable than it used to be but still quite rare and awesome in the form of double blessed clothes. I know you can dye artifact boots with Tokuno dyes, I have never tried regular boots. I have several double blessed pairs (not for sale, sorry).
Since we're on the topic, here's a few of the full outfits of matching named, double blessed old evil mage clothes I've got. All made and given to me by old friends back in the day who have long since quit, my most treasured possessions in UO.
