When clicking on the "Strange Plants" button without the right rare plants to give the trader will say one of the following things:
 * "These dye bottles? Sorry dear friend, these don't take coin. I only take the most peciouss and rare of flora in exchange for one of this!"
 * "Oh no no, this will not do. For these money is no good, you must return to me with a rare specimen of a plant!"
 * "You think you can pull a fast one on [Dye Trader's name], I don't think so! I only take the rarest of flowers for these special bottles"

Quotes

 * "I bring you the richest colors in exchange for your riches!"
 * "My dear, what you're wearing is much too drab. You absolutely must take a lesson in dyeing your tired attire!"
 * "The only kind of wood I would bother dyeing is RICH Mahogany. Dyeing any other wood is such a waste."
 * "You must do something about [Name of Pirate NPC]. Everytime he comes over here, it takes me a week to get the smell off!" (Only if Pirate NPC is present)

Trivia

 * Sprited by former artist William Data AKA Waffles.
 * Out of all the vendor NPCs in Terraria, the Dye Trader sells the least number of items, only 4.
 * The Dye Trader's comments about rich mahogany have been confirmed by Cenx to be a reference to the film Anchorman.
