Changing Page header in servicenow

[ihabeeb]

I am trying to differentiate DEV , TEST and PROD instances so that to avoid users mistakenly make changes to wrong environments .
I have created a custom theme (sys_ux_theme) and custom style(sys_ux_style) and changed the navigation headers and many other properties in style .
I also changed the browser tab icon in dev , so that it can easily identified
But i couldn't change the background color of page header. So now at DEV homepage , I am able to differentiate from PROD. But All the other pages look the same .
'"--now-unified-nav_header--background-color": "34,139,34",' - This is the property in style i changed so that it looks green .
I Also tried with theme builder , but couldn't change the page headers.
 How can i change each page headers ?
Is there a property (in style) for page headers ?

Hi @ihabeeb 

you are mixing two topics. The above demand form does not have a header and therefore you cannot change anything.

I often see this for many users and the reason is simple: You have to enable in your personal preferences that the navigation should always be visible:

After enabling, you will find on ALL pages the colorized page header.
