Because Nuln Oil is a black I wanted to try the wash Citadel had designed for blue; Drakenhof Nightshade. The colour itself is very good, perfect in fact, but the coverage is not. It doesn't flow as well as Nuln Oil, nor does it seem to provided the flat contrast one would want.
The Drakenhof Nightshade may be a better colour match for vehicles or larger models, but the mix seems thicker than the Nuln Oil, meaning it pools in the wrong places and sometimes doesn't staying in the recesses. It could be my batch - but as far as miniatures go, I'd stick to Nuln Oil for that dark blue look you're be after.
