Changing colors of Cascade Visual Effects

Talking about particles, i need to ask: If one day Niagara is ever released and cascade replaced, how we’ll edit particles already made in Cascade? Like changing colors of effects (specially of effects that are in Market place). We’ll be able to do this, or we’ll never be able to edit/modify any existing particle made in Cascade? At least the color of effects, wich is what i want to know, will be possible?
