Feature request: customizable color palettes

Currently we have a way to create, export and import styles. The styles can include custom colors for fill, line and text among other things like text alignment. Great feature.

I would like to have the ability to do the same for a color palette. In other words, I don’t want to have to pick a style to set the color of an object because that will necessarily also change text placement, etc. It would be nice if custom colors persisted in the palette provided and could be exported and imported.

Do you meaning the color palette highlighted below?
