When you're in Edit Mode, click on the block in question and choose the Design option.

In that dialog box, you can apply all the custom CSS (include background color or image) that you need.

On the last tab (CSS) you can even apply a custom class to cover the whole block, and then go to your external CSS file that your Theme uses and write styles for that particular class.

You can then save that style as a preset and easily apply it later to any other block should you so desire.

once you've created your block and saved it, you can select edit again and select "design"
