RX100 Postprocessing advice

Hi guys,

I have a particular question about the specific color effects and how to achieve them in post processing, like the B&W images with red only, green only etc. I am shooting RAW+jpg, since I find that the jpg gives me usable photos about 80-90% of the time. I am looking how to implement them in the latest version on Lightroom, but I haven found a way. Is it even possible?

Thanks!
