I am in the middle of setting up a new Sharepoint environment for a client and although I have customised the masterpage and css for the site I have not made any changes to the Suite Bar links or navigation area. Last week though I noticed that the font color of the Suite Bar links and the background of the navigation/login div has changed colour.
It's almost as though the theme has changed somehow and then stuck for those elements, I have made no changes to the CSS which could be affecting these. I have tried deleting and recreating the site collection but it is still incorrect when recreated.
The Office365 and Sharepoint Admin Centers all have the correct colours, but any Site/SiteCollection below them seem to be picking this colour theme up somehow.
Is there something simple I have missed?
