Changing Project Featured image background

Hi,
I would like to change the background of project featured image. Whenever i open a project, it shows featured image on white background which is not suitable as per the background of my theme.

Hello there,

Do you have a link to one of your projects to share here?

Try adding the below CSS code to Appearance > Customize > Additional CSS from dashboard.

    .single-jetpack-portfolio .post-thumbnail {
      background-color: #5e5e5e;
    }
