From the release:
The Citadel Edge Paints have been developed to help give your miniatures a final sharp, bright highlight.
These paints originally came as a request from the 'Eavy Metal team, but they're not just for use by the finest miniature painters in the world! In fact, matter what level of painter you are, these paints are designed to do one thing: help you to create great-looking miniatures by giving them a showcase-worthy finish.
Previously available in a limited set, they proved to be pretty damn popular. So, we decided to release them as individual paint - and they're available to buy right now.
There are 9 paints in the range, from Fulgrim Pink to Dorn Yellow. They each possess the same formulation as the Citadel Layer Paints, but come in a much lighter shade. This means they're the perfect colours and consistency for using alongside the rest of the Citadel Paint range. (So good are they, that some claim they were brewed by the master artisans of the Old World, but we'll not encourage such scurrilous rumours.)
