Vallejo Game Color: Dirty Grey 
A versatile neutral “dirty” mid-grey that’s perfect for quick armour panels, weapons casings, stone, cloth, and gritty weathering. Made to go on smooth with a clean matte finish.
 
What it does
Water-based acrylic made for fantasy & wargaming miniatures.
Newer Game Color formula is described as more fluid, more opaque, with high pigment saturation for stable colour.
Matte + self-levelling behaviour helps reduce visible brush marks.
Good everyday grey for basecoats, highlights, and “grim” neutral mixes.
 
How to use
Prime your model first for best adhesion and consistent colour.
Apply 2 thin coats for the smoothest finish (especially on flat panels).
Shade recesses with a dark wash, then re-layer Dirty Grey on raised areas for clean definition.
 
Best for
Armour panels, weapons casings, boots, straps
Stone, rubble, concrete bases
Mixing into other colours to “dirty down” highlights and make schemes more grimdark
 
ChalkyDot Tip: Dirty Grey is a killer “realism mixer.” Add just a tiny touch into brighter highlight colours to make them look more natural and less cartoony... especially on cloth and armour edges.
