This pull request updates the color sanitization regex within Color_Palette.php to support CSS variables. By integrating patterns that match CSS variable definitions (--variable-name) and usages (var(--variable-name)), we enable developers to use CSS variables in color settings seamlessly. This enhancement aligns with modern CSS practices, offering greater flexibility and theming capabilities. The update carefully extends the existing regex pattern, preserving all previous functionalities and security measures. It has been thoroughly tested to ensure compatibility with standard color formats and CSS variables.
