Coloured Dyes Removing: 'Shader effect'

[Earende]

I noticed this issue the very first time I tried applying dyes, and pretty much stopped using it since (not to mention you can't get some colours, or there is no actual black....)

It is easier to notice this with plate armours (GLA, MRD, PLD, WAR), like Cobalt Cuirass where the majority of it is shiny and all.

I always believed the reason for this is something like putting paint on cars - thus the shiny goes away. ;9
