Hello, I'm using a sopsolver to transfer color to particles and that has been successful. However, I want to delete either particles colored black or white. I've tried popKill and Wrangle with various expressions. No luck. Any suggestions?

I've fixed your project.
In attribute transfer in sop solver you should transfer Cd (which is color attribute) too not only temp because you wrote expression in pop kill based on Cd.
Note that when you're using pop kill you should check Reap Particles option box in Particles Motion tab and Behavior sub tab of flip solver.
