Create custom theme by following steps:

Navigate to menu -->sys_ux_style.list -->create new custom style

Name: Custom Style

Style  code:{
"base":{
},
"properties":{
"--now-unified-nav_header--background-color": "255, 0, 0"
}
}

2.Navigate to themes -->Create new custom theme there and name it  and set as shown in below picture

Now copy the sys_id from this custom theme page.
3.Navigate to sys_properties
Create new property there as shown in below and give the "copied sys_id" in value field.

Save and refresh the page .Now you will able to see the color change in the banner.

This works, but for some reason th dialog field when I favourite somethin changed to white and it stays white no matter what color I use in the UX style. do you know how I can change the color of that dialog field back to the default color?
