What determines (and how to change) financial report title font color?

Good evening, @DMDTCPA. 

Thanks for posting your question here in the Community. 

Let's check your Print Preview setup and your report printed in colors. 

Here's how: 

1. Hover over the Reports tab in the left menu, then choose Reports. 
2. Locate the report you're trying to print. 
3. Select the Printer icon on the top of the report. 
4. Click Print, then on the print window, go to the Color drop-down and ensure it's on either Black and white or Color. 
5. When you're finished, pick Print.
