Thanks for the kind remarks.

You can change the pallete using aseprite. As of the moment I am using sweetie 16 pallete. Pick any pallete to your liking from
lopsec pallete: https://lospec.com/palette-list . Then you can use something like aseprite to change the original color pallete to your own desired one(you can either use pallete from aforementioned site or use your own).
Its a quick  work you can see how to do it from here:

This way you can make several variant as needed. Hope its useful.
