Recently came across a new script now available in Pixinsight which can help colour Astro images without going to Photoshop, GIMP or Lightroom for advanced color processing
The Astro Color Mixer from @Cosgrove's Cosmos (Patrick Cosgrove) is now available as a script in PI updated for version Lockhart 1.9.4 . I have tried it for my Apple Mac Silicon setup and works seamlessly
Found the features very powerful and will be using this for sure in future processing
Thanks to Patrick for making this available.
