A lot of thought went into this color scheme. I wanted to do something that wasn't in any of the official pictures and had as much contrast as possible. Magenta, green, and orange are pretty much equidistant from each other on the color wheel. I'm so happy with it I'm not even sure I'm going to do any weathering.

Base Screamer Pink
Shade with glaze of 1:1 Druchii Violet : Lahmian Medium (several layers depending on depth)
Edge highlight Pink Horror
