Everybody listen closely. Indigo white is different from purple white.
Purple dyes have not been released to the game for normal users, but they are planned for a future release. I believe beta testers received special purple/pink dye at one point, similar to how some of us received special orange/red dye for participating in an old competition. Beta testers also have an exclusive crafting recipe for black/gold dye. (Jealous.)
The image with the purple dye on it is quite old, and many of the items shown have already been released, just with updated art.
Davion is the small guy with the cane on his shoulders and the black rope-like hair. (If you don’t know who he is, get the Aetherlight Bible! )
The Scarlet Man without his mask on in is the subject of many theories and many posts. I am of the opinion that it was a previous character design, but there is the possibility he could unmask himself to make a symbolic point at some time in the game.
