So after doing the flaming power sword effects on Roboute Guilliman, I was confronted with two more Primaris characters that had power swords. However this time they didn't have flames coming off the blade but looked pretty much like ordinary metal blades.
After some thought I decided to do something I was already good at. Rather than try any fancy streak effects or advanced effects, I thought of just making them look like they were super-heated and glowing.
What came to mind was what metal looks like when a blacksmith is heating it to shape and bend it. That orangy glow with the white tinge, metal that's searing hot and glowing.
So I simply took the identical paint palette and steps I used for the flaming sword and applied it to the plain blades.
I was really happy with the result! The blades look as though they they have a power source that's illuminating them but they also look intimidating because of how blazing hot they look. It was essentially one base coat of orange followed by a darker orange wash, followed by several successive drybrushes of lighter orange and yellows leading up to white closer to the blade tips.
