How to exclude Niagara Particles from Post Process Volumes?

I’m working on a game where you can destroy versions of the character. When you go into this ‘Destroy mode’ a post processing effect is added to make everything except for the clone black and white. However, I would also like to make the destroy Niagara particles colored as well, is there a way to exclude these particles from post processing?

I have tried a couple things, such as switching Render After DOF to true and allowing custom depth writes in the material used for the particle, but those haven’t worked. Any suggestions would be a big help!
