This plugin allows you to manage a site-wide central color palette for an uniform look’n’feel. The palette of the new block editor and the Theme Customizer are supported, as well as the classic editor. You can define this central color palette through the settings menu. All plugins that make use of WordPress’ color picker can benefit from this plugin as well.
This plugin supports a multi-site setup of WordPress.
Also this plugin replaces the color picker for choosing a text or background color found inside the classic editor with a bigger and customizable color grid.
For an easy migration between WordPress installations you can export and import your palette settings and colors.
