Change color to head...

I want to change the color #117CC1 that is in the head of Ninja Invoice white mark.
Do you know where I can do it from?
Thank you very much for your help.


Please put the Invoice Ninja logo back, you are in violation of our license.

The code makes this very clear, this is frustrating to see.

Most of the app styles are in public/css/app.css, if you make changes you need to run gulp
