A selection of guides detailing the colours I use for various coloured glass. These recipes can be applied to many differences materials and tweaked slightly to fit your style.

Green Lens/Gem

1. Basecoat with Caliban Green .
2. Paint the lower left or right portion with a layer of Warpstone Glow , leaving enough room for reducing its size 2 or 3 more times.
3. Paint a smaller area with Moot Green .
4. Add some Ice Yellow to your Moot Green and paint an even smaller patch, working further into your chosen side.
5. If you have enough room, paint an even smaller patch with pure Ice Yellow .
6. On larger lenses, consider painting a small Abaddon Black patch on the exact opposite side, leaving a swathe of Caliban Green exposed.
7. Finally, add a dot of white on the same side as the black, mirroring your brightest green/yellow highlight.

Blue Glass

1. Basecoat with Kantor Blue .
2. Mix some Russ Grey into your Kantor Blue and paint the lower left or right portion, leaving enough room for reducing its size 2 or 3 more times.
3. Paint a smaller area with pure Russ Grey .
4. Add some Dead White (or any other pure white) to your Russ Grey in a 1:2 ratio and paint an even smaller patch, working further into your chosen side.
5. If you have enough room, paint an even smaller patch with pure Russ Grey and Dead White mixed 2:1.
6. On larger glass windows, consider mixing some Abaddon Black into your Kantor Blue and painting a patch on the exact opposite side, leaving a swath of pure Kantor Blue exposed.
7. Finally, add a dot of white on the same side as the black, mirroring your brightest light blue highlight. Keep this tucked close to the edge, to prevent it looking too much like a gem.

If needs be, thin some of your Abaddon Black and Kantor Blue mix and carefully recess shade a thin line around the outside of the glass. This is to ensure is contrasts nicely with any surrounding metal.

Red Lens/Gem

1. Basecoat with Khorne Red .
2. Paint the lower left or right portion with a layer of Evil Sunz Scarlet , leaving enough room for reducing its size 2 or 3 more times.

4. Add some Lugganath Orange to your Wild Rider Red and paint an even smaller patch, working further into your chosen side.
5. If you have enough room, paint an even smaller patch with pure Lugganath Orange .
6. On larger lenses, consider painting a small patch of Khorne Red and Abaddon Black mix on the exact opposite side. Make sure you leave a swathe of pure Khorne Red exposed.
7. Finally, add a dot of white on the same side as the red-black, mirroring your brightest orange highlight.

Blue Lens/Gem
