Hellow young warrior !
Choosing those colors is an important thing.
First of all
Make a couple different miniatures, copy paste them on paint/toshop to get the overall look of a full unit.
You need to think about contrast AND homogeneity.
Will it be a cold color armor or a warm one ?
Using different color can really change the black aspect (ex : blueish grey like dark reaper & fenrisian grey will do a cold black, as the opposite is using eshin grey and administratum grey).
White helmet, neutral/warm metallics. You need a cold armor. Purple will do fine with either red or blue.(After years of testing & experimenting, I won't recommand ever using a pure chaos black for both base & shades)
I'd start with a base mixed : xereus purple
& chaos black
(1:1), 2 thin coats(or maybe Naggaroth Night with a little chaos black (3:1))
Shade with chaos black
overall highlight : Xereus purple
edge highlight : Genestealer Purple
over the top (for characters) extreme edge highlight : Lucius Lilac
or Genestealer mixed with pallid wych flesh (5:2)
I won't recommand the use of druuchi violet as a shade as it tends to warm up the balck (due to the red it contains) and sometime adds some shininess.
Maybe try with a diluted (w. lahmia) drakenhoff nightshade before/after highlighting ?
And wait for it to fully dry
before making any judgement call.
Bonus : paint bundle
Bonus 2 : Don't forget you can test "on paper" before applying any paint.Templates
exists on the internet.
