Armor dyes

So... Weapon dyes comes from bosses in monthly rotation, which begs the question "how often do they drop?"
But my main question is... what do drop armor dyes?

 

Are you asking what armor dyes do Bosses drop? Or what are the rates of getting a armor dye to drop from a boss?

 

Both questions are good for me. I wanted to know where to find armor dyes and with which drop rate... Also I thought weapon dyes dropped from bosses...

 

most bosses and mini bosses have armor dyes, they are rare items (red banner) so the drop rate is low. (but not as low as xtals )
the easiest armor dye comes from Lavarca, a normal mob

weapon dyes drop from all bosses at nightmare and ultimate difficulty.
they probably have the same rate as armor dyes, but since they are only available at high difficulty, they are more expensive.

 

Thanks, now: weapon dyes follow rotation right? Each month a boss has a different dye. What about armor dyes? And where can I find a thread similar to the monthly weapon dye drop list but that is for armor dyes?
