Modify banner background in NextExperience UI (San Diego)

I am working with the Next Experience UI for the first time, and am struggling to implement a seemingly simple change of the banner color in the new UI.  I have been able to create a new theme variant for the Polaris theme, and created a new color style to overwrite some of the OOB colors.  However, when copy/pasting from the OOB color style, there are hundreds of CSS properties, and it's difficult to know which ones control each UI component.  Following some other threads, I was able to change the primary, secondary, and neutral colors, as well as the now-color-chrome-brand properties to match my color scheme.  However, I'm not seeing anything that is affecting the banner itself:

Attempting to change banner colors in areas like basic ui16 or css system properties is not effective.  I have seen the docs for modifying several theme properties, including changing the banner image, but found them lacking for describing a simple color change.  Has anyone had any success with this that they can share?

Hi Matt,

You can try this:

  1. Define UX Style
    find_real_file.png
  2. Add this into Polaris theme (OOTB) --> trick here (m2m_theme_style)
    find_real_file.png
  3. Switch to use this theme
    find_real_file.png

    find_real_file.png


Hope this will help!

Hi Rohana,

Please check your instance if this is switched to use next experience (polaris theme).

Thanks, Jack. Yes. The Polaris properties is enabled. See attached image. Thanks!

Not sure, but, seems to be you are using only 1 theme.

Try to enable dark theme, then check again if you can switch normal/dark theme from Preferences menu.

Thanks Jack,

 

Yes, that's very helpful indeed.  

 

So essentially, the top banner color is controlled by the properties:

 

"--now-unified-nav_header--color": "<rgb value>",                          <----controls banner text color
"--now-unified-nav_header--background-color": "<rgb value>",     <----controls background color

 

And it looks like the background-color property can be modified with -start and -end properties if you desire a color gradient.
