Coloured Dyes Removing: 'Shader effect'

[Gramul]

Without reading text and looking just at the images, I have no idea what I'm suppose to to be seeing... or not seeing...

Well, maybe you should...read the text.

The devs thought dyes should remove sheen because it's more realistic.
Many of us are just wondering why, of all the things to center on realism, would you choose something like that?
When people dye things, they just want to change the color. They don't want to change the quality of the material. In real life, that's a downside of using cheap or inappropriate dyes/paints. Why bring that here?
