gw paints try this. These are older paint names I think but all I can remember off the top of my head. Im still using them
lol.
Make sure to water your paints down
First Layer: Tin bitz
Second Layer: Dwarf Bronze
Third Layer: Burnished Gold
Fourth Layer: Fine edge highlite with mithril silver.
Now for a little technique explination.
Tin bitz can go on solid.
Dwarf Bronze needs to be added carefully layer by layer. Leave the darker tin bits showing in recesses and such or where you want some shading. You can go over those areas with watered down bronze a little at a time to lighten them to prefrence. Add the gold on top of the bronze in a similar fashion. Now this might be a wierd step but sometimes I add a glaze shade or wash at this stage to blend them all together. I either use Agrax Earthshade watered down a bit or an orange glaze. The orange just makes it a little warmer.
Thr mithril is just for sharp edges to represent the light reflecting off the raised corner etx.
Hope this helps. If your interested in how this looms check my necron gallery. Used it a lot there. Im no professional painter but I was happy with the results.
Good luck and cheers.
P.s. typos my bad...wrote this on my phone heh
