Pretty much textbook color theory here, with the blue and red contrasting well against the yellow armour plate. A little more cleanup and highlighting here and there, and they'll be ready for the first sealant stage prior to waterslides and weathering (though the incipient snowfall means it may be a week or more before that's possible).
Tried out a couple cooler, neutral colors on the bases which I'm reasonably happy with. Toying with the idea of adding the occasional bit of litter and leaves here and there to jazz them up a little and give them a sense of scale. So far, so good!
