There's a question on where and how to find dyes on already on the site, but the answers don't seem to help me at all.
I'm specifically looking for the dyes related to Challenges – Mariner's and Lovely Dye. However, I'd also really like to be able to find Infernal, Abyssal, Purity, and Elegant Dyes as well. None of these have ever appeared for me, with any merchant, on any difficulty (I've tried Normal, Hard, and Expert, and am trying Master now. Will try Torment soon.)

According to the wiki there are a number of dyes that are only available after certain events. Two dyes no longer exist (Pale Dye and Rogue's Dye), and the Bottled Cloud and Bottled Smoke dyes are exclusive to the collector's edition. It should be noted that the vendor stocks will replenish after 15 minutes.
Below are all of the vendors:
It should also be noted that Javad and Rodger give a discount after their respective events.
