I have been wondering.. what color is Hector relax?

It just collector items.
Its not working anymore in-game, even will not give you advantages except for marketing stuff or just collect it.

But if you're asking about color of icon appeareance, i believe its quicksilver or perhaps pure.

hector relax has no color. It is the last known head texture of the person "hector( he had collected every single item ever in toribash).

Though now hector relax no longer works ingame (not sure if it used to earlier) and is more of a collectors item.
