Change the background color of image card in blog post

I'd like to change the background colour of this image block to white. It's on a blog post page. I've edited in site styles but no joy.

Any advice would be warmly received!

@Jen__ Would it be possible to share your site URL so we can take a look? Thanks!

@Jen__ The image block you mentioned is currently set as "collage". You may need to adjust the settings to "card" instead of "collage".

   Thanks for answering.
   
   Can you expand your explanation as I don't quite  follow. Are you saying I am working with a collage and not a card in my blog post? As per the editor, I think it is a card I selected.
   
   Where do I need to adjust the settings as you mention?
   
   I went into site styles and changed the collage styles as well as the card but no changes on the blog post yet!

I heard back from SS support and it's not possible to change the colour in the settings, they suggested CSS.

Could anyone provide? 🙏🙏
