Help! Need custom code help to change background color of card image blocks

Can you share link to page where you use image block? I can take a look

My client has created a cover page at the moment, so unable to access the actual site via the domain name.

How about if I take a screenshot of the main page instead? Will that do?

Have attached the following screenshots I took of the homepage of my client's site.
Showing the top & middle sections of her homepage, with the pink coloured background (just as a sample which my client was trying out)

She would like to change the background colours for each block to a different colour.
Just a recap again, the template used is Brine & the version is 7.0.

Difficult to help without checking url. You can wait for other members to support

oh ok.

will be happy to show the URL, but thing is it will only show the cover page, which my client wants to show at the moment since the site is not ready.

and when i try to copy & paste the link for the homepage from the dashboard, it shows the cover page as well. 

so in this case, how do i actually share the link to the the homepage itself?

Add to Home > Design > Custom CSS

div#block-yui_3_17_2_1_1585859981208_4615 figcaption {
    background: red;
}

Repeat for other blocks. Replace with block ID. See how to find ID. https://chrome.google.com/webstore/detail/squarespace-collectionblo/bggpdfnccodbnmcndckmeehdjkjojkde
