Citadel Layer paints are high quality acrylic paints that provide you with a huge range of colours and tones to choose from when you paint your miniatures. They are designed to be used straight over Citadel Base paints (and each other) without any mixing. By using several layers you can create a rich, natural finish on your models that looks fantastic on the battlefield. All Citadel paints are non-toxic, water-based acrylic that are designed for use on plastic, metal, and resin Citadel miniatures
