Okay, so I think I've almost got it.
I painted her chest armor with a darker grey and washed it and then dry brushed it with mithril silver.
I painter her arm with a lighter grey, and washed it and then dry brushed it with mithril silver.
I dry brushed the legs with mithril too, just to compare.
Not letting the wash pool helped.
Using a grey instead of metallic base layer also helped.
I think the chest armor actually looks pretty decent. (feel free to rain on my parade though).
I just got a new bottle of secret weapon amethyst wash (slightly darker than the secret weapon purple wash) which I will try out.
