Green OSL Tutorial

I decided to make a quick tutorial on how I paint the green glow effect (Object source lighting or OSL) on the eyes of terminators using the new Citadel paints. This technique is different to the previous tutorial, and also is designed for painting green glow on BLUE armour. The techniques I use are transferable to other colours of armour which I’ll explain at the end.


++ Preparation ++

So the armour is already painted blue, I’ve painted any areas that will receive the glow from the eyes, as well as any chipping or weathering. To thin the paints I use either Lahmian Medium, or Vallejo Airbrush thinner. Alternatively water can work, but I prefer the medium/thinner as I find the paint flows better and smoother.

++Step One++

The first step is to paint thinned Moot Green on the eye and around the eye, making sure to highlight any areas that would pick up the glow:

++Step Two++

I apply a glaze of Waywatcher Green. Glazes are different to Shades/Washes. They tint the area a colour and don’t darken/seek the recesses. Try to not use to much of this stuff, imagine it like a paint and use it sparingly. It should dry in a couple of seconds of applying it and it shouldn’t be pooling! I glaze the green areas as well as the blue areas around the glow.

++Step Three++

I then paint the eye with Moot Green, I use a detail brush here as this and the next two stages should be neat as possible!

++Step Four++

Flash Git Yellow is painted onto the lense, again I thin it a tiny amount to help it go on smoother

++Step Five++

I then use White Scar on the lense, I find painting from the middle outwards helps keep this neater.

++Step Six++

Once the white is dry I give the eye and surrounding area a glaze of Waywatcher Green.

++Step Seven++

Another glaze of Waywatcher Green is applied. You can see how the white, green and yellow have merged together now:

++Step Eight++

A glaze of Guilliman Blue is applied over the green areas and the blue but NOT the eye! Here we are toning down the moot green to tie in with the blue armour.

++Step Nine++

Repeat again with the blue glaze, but mainly on the green areas. You can see the difference already!

++Step Ten++

And a final third glaze of blue! The green is more subtle now and the eye stands out nicely!


++Other Colours of Armour++

I’ve successfully used this technique on red armour, following the same steps but applying a glaze of red instead of blue. The same should apply for most colours also. Remember you can make your own glazes using normal paint and Lahmain Medium, Vallejo Airbrush thinner or Glaze Medium.
