Last night I spent a couple hours working on Vanguard Vets., highlighting of their armor and then moved on to base coating grey in preparation for white. What you see below is the result. I stopped after the second Marine, because what I was seeing threw me off. (It's a quick and dirty photo, just to show color layout).
Originally, I'd planned to avoid the standard GW Raven Guard color scheme for veterans that uses all white arms and heads. I wasn't a huge fan of it, because I felt that pure white was a poor choice for stealth-oriented troopers. I decided to go with white decorations and pad rims instead.
After looking at the above Marines, I'm rethinking my plan. At this point, they look very odd to me. The scattered patches of white feel like they frame the black too much, especially on the shoulder pads. I selected fancy pads that had both open, flat areas to which to apply Chapter symbol decals, but that also provided white decoration. It's just not working out. I also selected helmeted heads that contained some sort of brow decoration that I could paint white while leaving the main helm black. Again, it looks really odd.
I'm not sure how to fix these guys. My first thought was to rip all the heads off if I can and paint them full white. But I think I'd still be left with the "picture frame" problem of the shoulder pads. So, perhaps solid white pads instead.
What do you readers think? White helmets with silver brow details, or black details? Solid white pads, or white pads with black details? The only thing that is off the table are solid white arms. Keep in mind that the jump packs will be attached eventually, adding more black behind the heads, with silver in the intake grilles.
