Hello! To my knowledge, there is currently no way to configure background colors and the example shown on the website uses images injected via markdown, ie:
https://www.dynatrace.com/support/help/shortlink/dashboard-component-annotation#images
You can also inject base64 encoded images using markdown! (see example attached)
You have full control over the appearance of content in custom applications and have our component library at your disposal as well, just for your information:

If you'd like to suggest an enhancement to our dashboard design options, I would recommend creating a product idea here: https://community.dynatrace.com/t5/Ideas/ct-p/ProductIdeas
Be aware, you'll need to be logged in as a Dynatrace user to access and contribute to this area of the community portal.
