Depending on how adventurous you feel, you might open your Output Setup pod and expand the Screen Layouts folder.
Good luck in figuring out exactly what to change!
I'm hijacking this thread - hope you don't mind.
I'm trying to change the color of the header in the Azure Blue layout. I opened the usersettings.js file (from the Output Setup pod) and found:
var backgroundColor = "#509de6";
I changed that to something different...regenerated the document and NOTHING CHANGED! I've searched everywhere. Where else can I look?
I'm so confused..
