You mean desktop version? It's the primary color. See the theme files.
In which file can I modify the style of the login, (form and text to display), the background color, I can not find how to edit it as simple html.
I would recommend reading this documentation:
ubuntu server 16.04
if you find out help me Akira I just want to change the background behind the logo, another thing I found interesting would be to leave the vehicle's popup horizontally at 970x150px
from the old interface I got Anton but from the new one I didn't
How do I change background color behind the logo in version 5.0?
Will I have to change more than one file?
