Blue: Scale75 Art Cobalt Blue, highlighted with that mixed with Pro Acryl Titanium White
NMM gold: Vanilla White as a base, then Primary Yellow washed over the top, then a shade of Burnt Sienna Umber, then an overall wash of Intense Yellow, then a further recess shade of Art Black, then working the midtones with Burnt Sienna mixed with Intense Yellow, then Titanium White in the highlights, then a wash of Titanium Grey to knock back the brightness a bit then Titanium White to bring just the edges back up. Phew. First time doing NMM gold. Went back over with some Permanent Orange mixed with Intense Yellow to warm it up a little more.
Base: Martian Ironearth, PVA glue and Noch grey ballast, a Noch Profi rock and a skull from the Citadel set.
