Brothers, I'm struggling

I am struggling so much to find a recipe for my wolves and it's getting quite frustrating. I've tried about 4 or 5 different color schemes and I can't find one that I really vibe with. I don't mind the baby blue standard color scheme but to me it's a bit too bright and a bit too clean. I've tried various tones of blue and grey and I just can't seem to get it. There was one recipe where I liked the color, it was mechanicus standard grey with drakenhof nightshade over it. I like the hue but I want to move away from using washes all over and I'm not sure how to replicate the color without drakenhof nightshade. I want my wolves more on the grey side with a slight blue tint to it. Or even the baby blue but a bit darker, a bit more grey, and a bit dirtier and gritty.

I just don't know what to do at this point.
