Unity ColourLovers Importer
There are options to edit and save the palettes returned. Saving a colour palette will create an asset in the Assets/Editor folder. Unfortunately Unity doesn't expose the ColorPresetLibrary so the preset assets are generated based on a text asset (ITS SO BAD BUT HEY IT WORKS).
Hopefully this is a handy little tool for prototyping/creating placeholder assets or UI to give you easy access to nice colour combinations instead of using default/random colours.

Tested on Unity 5.6, 2017 and 2018 and seems to work correctly.
