Citadel Screamer Pink Base paint is designed to give a smooth, solid pink color over an undercoat and for that reason this will almost always be the first paint you use on a miniature. Shake the pink paint before using (you can make this easier by adding an agitator ball).
The pink paint can be a bit thick sometimes and then you just add a few drops of water on your pallet. You really don't need a lot of water. Something to watch out for is to make sure you don't apply too much paint so that you don't start to hide details.
Another important functionality of this pink paint is that it not only covers the undercoat, but also covers other colors. So if you later miss something about this color, you can easily paint over it with this Screamer Pink base paint.
