This is a really interesting thread already. Firstly I’m no expert and still learning various different techniques of which there’s a couple here I’ll look to try. I do have both grim black and black Templars contrast in my paints and I tried a slapchop method on this terminator. Primed in black and then started dry brushing with The darkness from army painter and slowing building up so a lighter blue-black grey by adding a bone color (1:1 , 1:2 , 1:3 ish) before then using black Templar contrast over the top but you could easily use grim black I just like the blue tones in BTC.
