Splash and paint can look similar but are two different genes.. Splash is a blue gene. Paint is one copy of dominant white over black that creates pigment holes. I haven't personally seen them coexistent but figure just about anything can be bred in.
In splash only a portion of the feather may be black. In paint the entire feather will be black.
Here's a fun little calculator to play with and get some ideas.. not all things are included or may even be called something different depending on breed. Nor does it account for leakage.. but it's still semi-useful..

First generation Silkie crosses will be hard feathered.
Happy hatching!
