Reaper Acrylic Paint
The Reaper Triad system are a series of three complimentry colors, base, highlight and shadow and works in one of a couple of ways, Either pick the middle color and add the dark for the shadows, lights for the highlights or use the darkest colour as your base and add the lighter colours to get the desired highlights. Come in 1/2 oz. dropper bottles. They are meant to be dispensed onto a palette or other mixing surface and thinned a bit with water before use. Thinning a Master Series Paint for basecoating your miniature works well using a ratio of four or five drops of paint to one drop of water or flow improver. Other applications, like washes or layering, require more thinning.
Master Series are a thinner, more fluid paint, and will typically require two smooth coats (thinned as outlined above) to cover well. Because of this they excel at techniques requiring thinned paint, such as washes, glazing, and layering. If you are looking for a paint which can be thinned extremely, which resists separation of colors when thinned, and which has inherent flow properties to achieve beautiful smooth blends and delicate glazes, Master Series is probably your pick!
