Yeah, I guess.
GW has a way of painting showcase models that is... divisive.
I actually like the way they painted the ovals. Blue and brown looks nice to me.
I only have a couple of Age of Sigmar bases because they were the cheapest way to upgrade from square to round bases, and I figured I'd just adapt them to my usual basing method as I bought them to have round bases, not sculpted detail. I do use the
40k ones, though, and I am quite happy with muted, dark colors that give context to but don't interfere with the more detailed and brighter models on them. I'd be hesitant to choose garish colors for
GW's designs.
