How do i change the background color on CODE BLOCK

[Gordon Baird]

When i change the color theme on the Code Block Macro to "midnight" or "blacl", it still comes thru as light gray on all code blocks.     What am i doing wrong .  (note - this is using Cloud version)

Thanks

In Confluence Cloud New Editor, Code Block macro has been replaced with Code snippet.

Code snippet doesn't support customisation. It's been tracked as a feature request: https://jira.atlassian.com/browse/CONFCLOUD-66437
