Assia do you mean 1 time or 5 time useable pigments colors from Treasures of Tokuno Part II+III ?
Nope. There were two event arcs where you could dye items a nifty color via colored slimes. One was for the asian shards and one was for the rest of the shards. The asian slimes were 5 shades of purple, gold, green and blue and let you dye items like a cloth tub. Everybody tried to come up with items other than standard cloth, bolts and bags to dye. Some people chose minor rares like spring cleaning shirts, clothing artifacts, Dbl Exceptional clothing, snowmen, piles of wool, etc. Sometimes you can find these items floating around and the special color adds a bit of value to the items based on the color and if it can't be replicated. The two-tone blues and the brightest gold are the most obvious.
For the other slime event, it was different colors and it worked a bit different.
