Describe the issue you are experiencing

As you can see, when enabling Show colour in compact tab bar in Safari browser the colour follows primary-color instead of the theme colour.

Describe the behavior you expected

It should follow either, primary-background-color or secondary-background-color instead of primary-colour, otherwise this will change the UI text colour as it's linked to primary-colour (for some strange reason?), which will make text unreadable.

Steps to reproduce the issue

1. Enable `Show colour in compact tab bar' in Safari.
2. Navigate to dashboard frontend.
3. See Tab colour not matching theme.
