Hello. I am using Light Mode only, and I changed the Accent theme colour in Theme Studio: Colours to 
000000 for the active row. The built-in Divider component still displays as blue in preview and in the browser (Safari).
I checked the Divider in the Inspector. It has no custom classes and no advanced code. I also checked the parent components in the structure and found no custom classes, borders, or overrides.
The Divider resides at the end of the following path: Wrapper → Flex → Footer grid with 3 containers → Divider.
I was hoping that the Divider would inherit the current (custom) Accent colour, but it does not reflect the change.
Is there another setting or known issue that could cause this? Do I need to recite all the monarchs since Aethelred the Unready? 
Can you show us a screenshot of your settings for the divider, as that would help diagnose the problem?
Did you OVERRIDE the accent colors?
Hi. Thank you for your reply. I’ve just taken a look at all the settings in order to upload a screenshot – and in Background, the colour was set to blue, which I changed to “accent” and now it is the right colour, both in preview and in the browser. Problem solved. I had thought that background meant background, not fill.
cheers
