With the silver done I picked Magic Blue for the trim and highlighted it with Electric Blue. Her hair is Calvary Brown and Wild Rider Red, which is my go-to for red hair. Betty's skin is just my own flesh mix, Reikland Fleshshade, and Basic Skin, and her lips are Purple Shadow. Amazingly I got her eyes right in one attempt, so yay!
Betty's old-school raygun is just Averland Sunset and Deep Yellow, with some thinned Sepia Wash to shade it. The end of the barrel is a bit bent but I daren't try straightening it in case it snaps off. To break up all the blue and silver I did her holster to look like leather with Chocolate and Flat Browns.
I wanted to do her base as an alien planet, and it was a doddle: just some Vallejo Black Lava texture paste, painted Violet and washed with Druchii Violet. I used Purple mixed with a touch of White to highlight it. Then I painted a couple of tufts — one Scorpy Green and Light Turquoise, the other Red and Averland Sunset — and stuck them on.
The other building is all done and I'm writing up the post, so come back soon!
