SmartSheet bar at top of dashboard


I've created a dashboard that I use in SmartSheet and have embedded in our project's SharePoint site. Unfortunately, at the top is has our logo but the background color behind it is so dark, parts of it blend in. (see image below) Is there any way to change this? I've gone to Personal Colors& Logo but it only changed it for the main SmartSheet menu pages. When I open a project plan/report/dashboard, it has the bar at the top, below.

Any help would be appreciated.
