[eddieataberk]

Describe the project you are working on

Game with multiple color themes

Describe the problem or limitation you are having in your project

Having to re-arrange swatches is time-consuming

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add the ability to save and load swatch groups as tres files.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

If this enhancement will not be used often, can it be worked around with a few lines of script?

no

Is there a reason why this should be core and not an add-on in the asset library?

this is about improving the editor usability

Maybe not for this proposal since PR is already in the work, but as a future improvement, a Quick Load similar to other resource Quick Load popup (list all assets with the correct type) would be a nice complement to the classic Load file popup, and would make the color palette picker as fast as Unity's swatch library dropdown.
