Helix Nebula

Please feel free to share any pointers on processing the Helix Nebula for this is my very first image I’ve processed using FITS files after joining Telescope Live. I received the subscription as a Christmas gift from my two sons and started using Siril to process the files from an observation bundle I downloaded. The files came from an 8 hour bundle with LRGB filters. My first attempt in using Siril, had the center area pretty green in color and second try brought out more of the blue you see now. The colors really popped when I used MS Picture manager on the second Siril image. Clearly, I have a lot to learn so any pointers would be appreciated.
