Get colliding particle data?

More precisely, I'm trying to get the color of the colliding particle from the object it's colliding with. I can't just grab it from the particle system since the startColor's randomized.

All I found in the API is CollisionEvents which seems to expose things like normals and the collision intersection but not much else. Am I missing anything?

I'm worried I'll have to split my particle system into multiple ones.


Edit : Ended up going with multiple systems using one color per.
