How can I remove the background border from my Craft theme collage?

Hello everyone! I was wondering if anyone knew how to remove the slight background/boarder behind the collage? It changes the color when I go to theme setting>color>also used for text links>background 1. When I change it to transparent it goes black around the boarder of the picture. I would really love to get rid of it as my background kind of shows the boarder no matter the color I choose. It is the last section of my website (6 pictures) and its also on my clickable pictures/products under my different categories . Thank you!

Hi @moderndayrags
You can try follow this path:
Themes => edit code => asset => base.css
and add this code to bottom of the file base.css

.collage-card {
background: transparent!important;
}

@ExpertRookie That looks like it will work for my home page collage (has a slight hue but not like it was) but it didn’t work for my product cards. Do you by chance have a code for that? Thank you!
