MSP Core Colours Singles are the mainstay of the Reaper Acrylic paint range. Hundreds of colours, they mix easily, go on smoothly and dry matte. Specially blended for shading and layering, they work best with their own flow improver and drying retarder.

Personally I’ve also used these with Citadel Contrast Paints, very old Citadel Paints, Scale 75, Darkstar Metallics and Vallejo glaze medium. All these mix well and have never caused a problem or reaction.

However Scale 75 grey surface primer does cause them to flake up a little. Stick to the Reaper Primers for trouble free painting.
