Thanks! Range of paints. Well the general answer to that is GW
the more specific answer is a mix of codex grey and catachan green for the undercoat and then the same mix with in successive layers with more sunburst Yellow added to each. The final highlight is codex with a touch of white, dark flesh, and vomit brown.
Reds are dark flesh highlighted up to blood red and washed with delvan mud to tone. The rest is a pretty standard metals mix with boltgun and mithril silver and delvan mud wash.
