Here’s how I paint my industrial yellow Space Marines. Yellow is a notoriously difficult color to paint, but I use a simple base coat of Averland Sunset, followed by a dark wash and progressively lighter yellow drybrushes. This example Terminator features hazard stripes painted with Corvus Black and some custom paper warning sign posters.
