Guild Wars 2

With the recent dye packs that have popped up on the gem store, there are 12 new dyes that were also added to boot. Six for “frost” and six for “flame.” Here:
<https://www.guildwars2.com/en/news/red-hot-new-items-in-the-gem-store-now/>;
It says that the dyes are “exclusive flame or frost colors.” Does this mean that the colors are only accessible through the gem-bought dye packs for a limited time? Or by “exclusive” do they just mean new? Meaning they can they still be picked up in unidentified dyes at a later time?

The way that is is worded pretty much implies they won’t be around once the dye packs are no longer on sale.

I still serioulsy hope that is not the case. A lot of people want to collect all the dyes and if some are removed, it will become awful.

My understanding of exclusive means that they can only be purchased from the one outlet.
