You can set an overlay color for the cover image. This means that you cover it with a semi-transparent colored box. Also, you can edit the overlay color contrast — the difference between the colors of the cover image and title.

To start changing the cover image settings:

  1. Hover over the cover image and click Preferences.

  2. In the opened window, select the overlay color on the palette and manage its contrast with a slider bar.

  3. When you are totally okay with the cover image appearance, click Done.
