Getting a squad of Primaris Hellblasters has given me an excuse to play with some plasma glow effects. I’ve previously used drybrushing over the raised coils to get this effect, and it’s a quick, easy way to do things, perfect for beginners getting the hang of lighting effects. It can, however, leave a chalky finish. Impressive glow effects can be done with an airbrush but since I don’t have one of those, I’m keeping the hairy stick approach.
First off, I checked out the Warhammer TV approach. I found this okay and easy to follow, but I felt it gave too strong a contrast between the coils and it was very easy to make mistakes, mostly overstepping from raised coils into recesses.
After trying a few things, I settled on focusing the brightest glow around the centre of the weapon in an ellipse – white at the centre, moving into darker blue towards the edges. Provided you thin your paints (absolutely essential, otherwise you’ll get stark transitions between colours), this is quick and easy to do, and you don’t need to be too tidy. In all steps, make sure you get your paint into the recesses between coils. This is what we’re aiming for:
Step 1: Base Coat
Start by base coating the plasma coils in Vallejo Magic Blue (GW Teclis Blue). It works best over white (this will be brighter) but I went over Caliban Green as that’s what I’d used as a primer.
Step 2: Outer Ellipse
Using Vallejo Electric Blue (GW Emperor’s Children), paint a wide ellipse across all the coils. The top edge is your mid-point so half your ellipse should be on the front and half on top. Do the same on both sides of the weapon so that the outer edges of the ellipses should almost touch in the middle on top of the weapon.
Step 3: First Highlight
Mixing Vallejo Electric Blue (GW Lothern Blue) with white (any brand will do), paint a smaller ellipse within the outer ellipse described in step 2.
Step 4: Final Highlight
Paint a thin line of white along the top edge of the plasma coils. When you get to the centre of the ellipses, widen your line just a touch so it looks like the source of the light comes from here.
Step 5: Tidy Up
If any of your transitions between colours look too stark (like above where I overstepped with the white), use a very thin layer of paint (about 70% water) to smooth them out.
Another option is to move the ellipses along the plasma coil. In the below example, I painted them nearer the barrel to give an impression of movement, as though a shot was leaving the weapon.
