Hello. This is a side-project I worked on while my main project was on hold for a little while.
Palette Pallet allows you to easily create palettes that you can then import into Fusion to replace "defpal" - the default palette.

It has been designed to be as easy-to-use as possible. There are several features, including the ability to pick colours from external images, paste hex codes, and import palettes or swatches independently of each other.
