The Custom Color Palette for Gutenberg is a WordPress plugin that enables users to personalize the color palette within the Gutenberg Editor. This plugin replaces the default color options provided by WordPress Core and the active theme, allowing for a more tailored design experience. Users can select and modify colors across three distinct categories: Main Colors, Grayscale Colors, and Primary Colors, providing a robust selection for various design needs.

This plugin is designed to work exclusively with WordPress 5.0 and the Gutenberg plugin, ensuring compatibility with the latest editor features. By utilizing CSS variables for color changes, it enhances the visual customization of documents created in Gutenberg. However, it is important to note that this functionality may not be supported in older browsers, such as Internet Explorer, limiting its accessibility in some environments.
