For a purple-ish pink, I would use the following:
Base: Screamer Pink
Accent: Pink Horror
Outer accent: Emperor's Children
Edge accent: Fulgrim Pink
or
Base: Pink Horror
Ink: Carroburg Crimson
Accent: Pink Horror
Outer accent: Emperor's Children
Edge accent: Fulgrim Pink
Edge accents aren't necessary. They are meant to simulate light reflexions.
