To get to Custom Colours, go into Settings > Editor > Colors > Custom Colors
Administrators can control custom colours in the colour pallet to ensure brand guidelines are adhered to. This setting allows you to enter hex values of your brand or remove ones no longer needed. These settings are rolled out against all of your accounts.
Simply enter the hex value for the colour and click "Add". When you’re finished click "Update" on the same page to save your changes.
Enabling custom colours
To enable custom colours, go to Settings > Editor > Colors > Enable Color Entry
Administrators can control if the user is able to add custom hex values into the colour pallet in the editor. This is useful for brand compliance as you may want to restrict users ability to enter colours different to your corporate brand.
On - Enables colours outside of the pallet
Off - Disables colours outside of the pallet.
