I have a rather extensive collection of dyes, I've never used them on 3 ascended, final armor characters. But today I thought I'd experiment on my naturally green armor. After all I've read on dyes I was quite surprised. In 7 tests on my armor here's what I found.
dye remover - nothing
red - red
blue - blue
yellow - yellow
silver - silver
green - green
orange - orange
The present color of the armor meant nothing... the dyes worked as they appeared they should. Has this been fixed or have the countless threads complaining about weird dyes been limited to dyeing weapons (or limited to only mixing dyes)?
edit:
orange dye turned my scar purple

edit:
then silver turned it a pretty shiny light green
