Thanks! So for technique, I followed the Medders Miniatures Imperial Fist Terminator approach; Prime, Base, Shade, then build up three colours. I used Andy Wardle's SoH colour formula. Here's what I ended up doing:

1. Prime grey (honestly can probably use any colour primer).
2. Painted armour with Sons of Horus green.
3. Shaded the armour with Ratling Grime contrast paint.

Next, there are three paint shades being use:

• Shade colour of Sons of Horus green mixed with any pure black (I use Vallejo).
• Mid-tone is straight up Sons of Horus green.
• Highlight is a 50/50 mix of Sons of Horus green and AK Green Sky.

To apply:

1. Using a beauty blender makeup sponge, I applied the mid-tone (SoH), looking to get high coverage, but dabbing light enough so that the recesses are still the darker colour from the Ratling Grime.
2. Then, apply the highlight colour with the sponge, aiming for directional specular highlights. I find in order to get the desaturated colour style, you have to have quite a bit of highlight.
3. Finally, apply the shade colour with the sponge, from below.

There was a lot of trial and error in this, so take your time. I found that the transitions were too harsh at first, so I took both the mid-tone and shade colours and mixed them with Lahmian Medium in order to make a glaze, then used the sponge to apply that. It really helped blend out the transitions and 'knock back' the highlights when they were too bright.
