I've been using this method for a while and thought I'd share it with the rest of you. It's pretty simple (and I'm sure it's been thought of already) but I don't see a guide about it so here you go.
Find Your Dye

Search For Your Dye
Guild Wars 2 Spidy
Create Your Link
Guild Wars 2 ID
Preview It In-Game/Buy It/Enjoy!
- For example, if you wanted to preview Celestial Dye you would look it up on spidy:
Guild Wars 2 Spidy - Celestial Dye
- Copy "20359" into gw2id to get this link:
[&AgGHTwAA]
- Copy that, paste/whisper it to yourself in-game, and right-click to preview. If you like it, buy it and enjoy.
A little side-tip. Since this is only the chat link, you'll have to right-click/preview it multiple times to fill up the 4 dye preview slots. Afterwards just right click on the picture of the dye and click "Clear Preview" to remove it from the undesired slots. If anyone figures out a better way feel free to post it and I'll update this post. Hope this helps some of you out there finally find that color you've been looking for!
