Regarding additional color palettes…
I found this method to add custom palettes.

Pretty easy to follow.
Found some nice ones for Thanksgiving, Valentine’s day, St Patty’s day, etc.
I need to be at home to test them, but all indications point to success.

Excellent. Thank you. I will use that to experiment with making my own custom palettes.
