I'm toying with the idea of zenithal lighting on my Sons of Orar, having recently invested in an airbrush and compressor. I've not used it at all yet so no idea if it's any good (it's not a branded
AB and only cost £12).
I've done a little google-fu and have found good info on silver zenithal lighting though nothing on red, I'm looking for hints and tips on which specific shades of red to use (hopefully ending up with a blood angels shade). The rub? That'd be the white helmets and shoulder pads - I'll have to paint these separately, off the miniature, though how can I then tie that in with the appearance of the rest of the mini?
Any recommendations on specific colours to use? I can already hear you shouting "VALLEJO!" you know

Specifically which colour names though would be really helpful!
Another question that's just come to mind - as squad markings are the knee caps, would ZH even be the right technique? I imagine that if I put all this effort in to ZH and then blobbed on some white knee pads it'd look a little odd?
