There's a distinct header style employed when a page enters what we term 'Focused Content Mode.' During this phase, certain header links/buttons are muted to enhance the emphasis on video content. If you wish to change the header background colour in content mode, navigate to the Theme Editor and adjust the value under Page > Content Mode > Header Background Colour. The system will automatically generate a palette of colours based on this background, muting the header nav links and buttons.

This behaviour is the default setting. Alternatively, if you prefer the Focused Content mode style to precisely match the setup for the rest of the event pages, set Page > Content Mode > Header Background Colour to the exact colour as your Page > Header > Header Background Colour. When the system recognizes identical colours, it won't auto-generate the muted palette, reverting instead to your base styles and colours for the header nav links and buttons during the Focused Content Mode.
