How do I paint the roof of the Stormreach Portal to fit in with my army aesthetic?
So I have a rough idea how I'll paint most of this, but I'm kinda stuck on the roof - using a black primer, with the metallic sections/sigmar faces I'll drybrush warlock bronze followed by a lighter drybrush of screaming bell, likely with an aditional drybrush of retributor armour on the sunray-like thingies on top of the sphere
the stone I'll paint eshin grey with a drybrush of administratum for a dark looking stone look I've grown to like, with tesseract glow in the astological lines between the smaller orbs in the walls - portal will be white to act as a base for some more tesseract glow (glowing portal sounds cool to me) and the braziers would be green flames using tesseract glow blending to hexwraith and then to warp lightning, likely with some caliban green and abaddon black at the tip.
but what I'm really stuck on is the roof tiling, I want it to match with the warp lightning green I used for the cloaks but I'm unsure how to make the roof tiling look good - would warp lightning followed by nuln oil help the tiles on the roof to pop out or would there be another method you guys would recommend?
