Here are some of my latest mechanicum models painted up a bright color. Mechanicum blcan often be a very dark army with all the metal so wanted these to stand out.
Armor is Given a base coat of GW Thunderhawk Blue, then Sotek Green, then Temple Guard Blue. An oil wash of Paynes Grey helps draken the shadows back down and with oin washing and panel lines.
Metals were with Vallejo Metal Color Magnesium, Army painter gunmetal, then some Paynes Grey oil to darken it. Rust was thinned combo of Burnt Siena and Burnt Umber.
