As part of painting up a Mordheim gang to use in our campaign I experimented on some of the many Orks and Goblins I owned but never had painted or even assembled in most cases. I tried four color schemes, in the end I opted for black with purple flames and black with blue flames as I think it looks eviler. Everyone else does yellow or red or orange flames. I tried it and I thought blue and purple looked better.
I had two Warhammer boxed sets worth of (Night) Goblin archers (plus more!) and I decided to break them into two units, a big unit and a bigger unit. I also had enough command and fanatics to max out points wise. Despite getting some help and encouragement I was dismayed to learn that literally hundreds of Goblins isn't even a 1000 points.
Many years later I used the bigger of the two units of Night Goblin archers in a Warhammer 8th Edition Mighty Empires campaign at the FLGS. They were allies to my all metal Nurgle Daemons army. I don't think I won a game. But I did write several blog posts. In 2019 I finally got my miniatures and paints out of storage and the first thing I painted was monopose Goblin spearmen, because I have so many. The archers are done, even the command for the Goblin spearmen is done.
Now Warhammer doesn't use square bases and some of my goblins will be pressed into service as Gloomspite Gitz Warcry gang. Now GW has brought back square bases and some of their old models and armies, I'm still not playing Warhammer, even my Warhammer 40,000 playing is limited but I slowly paint. I never thought I'd be famous for Night Goblin paint schemes, but I will return to painting purple flames again, right now I'm on tiny lines and my never ending rebasing of my Chaos Space Marine Renegades, the Long War never ends.
