Details as to the model mix, and the focus of the codex are scarce at this time, but look for GW to leak more info as the next few months roll on, until the final big splash release in April!
Needless to say, this much anticipated release has been the subject of much speculation over the last few months, after GW removed the models and codex books for sale form their stores. The rumour mills are churning, and there is much slathering of lips and champing at the bit... what is a Grey Knights Player to do in the meantime?
Well, I'd suggest trolling the web for some cool pictures to inspire and increase your agony waiting for their imminent arrival.
So, to start, I offer up one of my own Grey Knight models for your consideration.
The steel bits were base coated with Chaos Black. I then layered equal parts GW Chaos Black and Boltgun metal, Boltgun metal, and Chainmail. These were done with layered feathering, to change texture from the softer warmer metals and make it look more stark and severe, and to simulate a sharpened edge - which is further enhanced by the filing job I did to reduce the thickness of the blade edge. Again, to tie the tonality, I glazed it with very thin black ink
The gold bits were base coated using Scorched Brown. I find the red tones in the brown help make gold and brassy colours pop a bit more, and it is warmer visually than painting them over black. I then painted on Tin Bitz, Dwarf Bronze, and Burnished Gold, blending the intermediate stages as I went. I washed this together using a thinned down brown ink, as a glaze. This ensured the tone remained uniform. I then directly painted the crevasses with undiluted brown ink to make them more bold. Finally, I made some subtle "bright" highlights on the higher textures, to make it have an aged shine.
The green laurel started with Dark Angels Green, and I picked out highlights with Snot Green, then Goblin Green, and finally gave it a unifying glaze with thinned green ink, followed by a darker wash to pick out the crevasses and details.
The red details all started with a base coat of Scorched Brown. Again, this is because of the red tones already in the brown, which help the red go on more easily, and help keep it warm and brighter. I blended upwards from Scab red to Blood red, adding a touch of Snakebite leather to the red for a final highlight, and edge highlighting.
Though difficult to see, and very small on this particular model, the eye lenses were painted with a red gem effect. This started with Chaos black, highlighted up to Scab Red, Then Blood Red, and finally Fiery Orange. I glazed this with a Purple Ink, and gave it a tiny white dot to simulate the reflection spot.
The white detail bits started with a Shadow Grey/Skull White mix, and layering on more white. I kept this thin and did multiple coats to ensure better control and a smooth finish that does not look chalky, a problem all too common with white painted models.
Finally, the paper, purity seals, and scroll work were base coated with Graveyard Earth. I then layered an equal mix of Bleached Bone and Graveyard Earth on top. Finally, I blended in pure Bleached bone, up to about a 50/50 mix of Bleached Bone and Skull White. The scroll work lettering and detail was painted on with a 50/50 mix of Chaos Black and Brown Ink. The ink helps thin the paint to ease the freehand lettering work on the name scroll, as well as allow fine lines to simulate written passages elsewhere.
When painting the base, I wanted to ensure the model stood out, and didn't blend into the base. To do this I used some slight contrast by painting the concrete in a reddish pallete, and the dirt with a reddish brown. Queuing off the red detail on the Terminator also helped create a colour triangle which draws the eyes to the core of the model. The reddish colouration was intermingled with grey and bleached bone, blended, overbrushed, and drybrushed to simulate a dusty ruin, without over accentuating the base.
Hopefully this has been inspiring enough to make you go off in search of more pictures of Grey Knights and start working on your own!
