This dye combo is intended to replicate the colours of Ambrite Weapons (Dry Top rewards). It focuses on the tarnished bronze base colours with amber/orange highlights.
The dyes selected are some of the recommended ones for Medium armour, but you may be able to replicate this on Heavy/Light with slight variations. Staying under the Brown and Orange hues will help you nail down the dyes that work well for your armour. Light armours may need to focus on darker dyes to replicate the effect.
The screenshot includes Illumination as a highlight on my boots, but that’s not really part of the set and can be ignored (I just wanted the knives to stand out and look metallic).
