There are specific slots that are able to be dyed, and it's generally the slots where dying them would actually matter (ie they have some surface area to be dyed).The dye system is also not a tinting system. And by that I mean we don't apply a color shift to the entire piece of armor. Each piece of dyable armor is specifically designed and built with certain areas that can have their color changed. It could be as simple as a strip of cloth running down a chainmail chest piece, or as complex as an entire robe. We hand craft and designate these areas, and in combination with specific colors we've chosen, we can allow players to have a lot of additional visual variety, while maintaining a controlled look and style to the game.
They're technically a two color gradient, which allows us to achieve a more natural looking coloration, but for the sake of simplicity, yes they're presented as a single color.
I think the idea of having dies apply effects in different ways is awesome, but don't forget there are plenty of other things going on gear that could be the basis for those types of effects as well.
