Improved Colour Settings for the paragraph block

The paragraph block supports Colour Settings which are defined using add_theme_support( 'editor-color-palette').

The genesis-a2z theme now has 15 standard values; 11 – as provided by the WordPress core version of Gutenberg, plus Vivid Purple and White, and the two colours that can be configured by the user in the customizer Link and Accent.

White on Vivid Purple.

Since Link colour and Accent colour are the same then both of them get ticked when you choose one of them.
