Change product image background color Dawn Theme

[hoodieharmony]

Hello! I'd like to change the background color of the images shown on the collection to have a background of #F1F1F1, but I can't seem to figure it out.

 (I'm using a temp collection to distinguish the background color)

Hey @hoodieharmony,

Sorry I'm not understanding. The color is already #F1F1F1. What is it that you are looking to change?

[hoodieharmony]

Apologies. I will show you what I mean:

I was using that example image in order to show you what area I wanted to recolor. Here is what the actual collection looks like:

As you can see, the background color is white and I have no idea how to change it.

Oh I see, but we can't color the background of your collection because the image you used is a .jpg. You need to have .png without backgrounds.

Assuming he had a png with a transparent background, what would the css be? I'm also trying to add a gray background to my Featured Collection images and product images. I have a png with transparent background. Thank you for your help. Dawn theme
