[Suggestion] Ability to color each armor attachment separately

[Feltal]

Whether armor pieces have metallic parts on the accents channel or not can be a make or break for some sets like the Tennocon 2018 armor, hulta armor, gazal armor, etc. I'd like to suggest either generally migrating all metallic parts to the accents channel, or a preferable option would be to allow us to color each attachment individually like the syandana (which was a great change).
