SharePoint Homepage News Roll Up Wrong Colour

Hi everyone,

I wonder if anyone can help.

I have an issue where the theme colour assigned to the SharePoint Home site is not been reflected in the rolled up news colour.

I have attatched some screenshots that show the purple theme assigned to the Home site and the green that is been shown on the rolled up news.

Does anyone else have this issue and found a fix?

Hope you can help.

Karl
