Vallejo Game Color: Sick Green 
That perfect nasty, diseased green for plague skin, toxic cloth, swampy monsters, and grimy armour. Dark enough for shadows, but still green enough to feel “alive.”
 
What it does
Water-based acrylic made for fantasy & wargaming miniatures, designed to brush on smoothly.
Dries to an opaque, matte finish with good control for both small details and larger areas.
Reformulated Game Color is commonly described as high pigment saturation with smooth, self-levelling application and strong adhesion on common mini surfaces.
 
How to use
Shake well (greens settle... give it a good mix).
Apply 2 thin coats for the cleanest result.
Shade the deepest recesses with a darker green/brown wash.
Re-layer Sick Green on raised areas to bring the “sick” tone back.
 
Best for
Plague / Nurgle-style skin, boils, pustules, infected cloth
Swamp creatures, slimey bases, mossy terrain accents
“Grimy green” shadows under brighter highlight greens
 
ChalkyDot Tip: For instant “infected” depth, glaze a little purple-red into the deepest cracks (around wounds, under folds), then bring Sick Green back on the raised skin. Green + subtle purple makes it look painfully organic.
