@Guerreiro64, it would be much easier for non-tech-savvy users to import a palette via ‘‘Settings’’ >> ‘‘Manage Resources…’’ >> ‘‘Import Resources’’, AND this works on every operating system.
@Sydney: Guerreiro64 described a neat way to create a palette, but in case if you want to do it in Krita, then, in order to get a palette that is permanently available to you, you would also have to create a regular palette in the Palette Docker. The “palette” in the ACS is only a temporary snapshot that shows the status of the colors currently present in the image.
This means, that, if it has to be a palette, you have to pick up the colors individually in the ACS and insert them into a new palette in the Palette Docker, or attach them to an existing palette.
So, the Krita-way is not a straight way, but works.
Furthermore, you could use the “TF Easy Colors Map” plugin from @TigerForge as an alternative, I think it serves this purpose as well.
