Even though Google Calendar no longer has theme support, GMail still does.
I had mixed success using the same theme in Calendar as Gmail (using https://github.com/padster/CalendarThemeExtension v1.0.15).
Simply taking the URL of the preview image from Gmail theme works really well. For example HighScore theme preview URL: https://ssl.gstatic.com/ui/v1/icons/mail/themes/highscore/previewHD2.png
The actual theme is 3 files, the main one being https://ssl.gstatic.com/ui/v1/icons/mail/images/2/5/highscore/day_background.png
The best technique I found for URL determination is to use Firefox and Page Property Info (media) view, and review backgrounds.
Both these work really well
Using a site or tool like https://www.base64-image.de/ can upload a copy of image and then copy/paste the result.
This does NOT work for the 20Kb preview image (suspect it is too large, unclear if this is a bug or behavior).
This works great for the main theme image which is tiny (2Kb), e.g.

Thanks for making this available! I'm not usually into themes but I needed a way to keep different accounts visually distinct on my machine.

Partially working - base64 encoding
Using a site or tool like https://www.base64-image.de/ can upload a copy of image and then copy/paste the result.
