A water-based acrylic speed paint designed by Games Workshop to base, shade, and highlight miniatures in a single application. 
Capillary High-Flow Medium: Utilizing a low-surface-tension medium, the paint behaves like a heavy wash. Capillary action automatically pulls deep forest-green pigments into recesses while leaving a thinned, translucent layer over raised surfaces for a natural highlight.
Completely water-based and non-toxic, making it safe for indoor brushwork. It requires thorough shaking before use to redistribute settled green and yellow pigments.
Undercoat Performance:Because it is highly translucent, the primer choice heavily dictates the end tone:
White / Grey Seer Base: Produces an intensely bright, high-contrast, luminous finish ideal for sci-fi armor, gems, or toxic vials.
Wraithbone / Off-White Base: Pulls a slightly warmer tone, accentuating the yellow undertone of the paint.
Brown Pre-Shade Base: When sprayed over a brown undercoat via airbrush, it forms realistic, deep transitions suited for jungle camouflage or specialized Space Marine armor.
