- Google Calendar appears to be introducing monthly background colors.
- Analysis of the Android “Google Calendar” app update v2026.26.1-943790361-release has revealed new resource code for 12 monthly background and button colors.
- There is a high possibility that monthly color schemes will be coming to Google Calendar.
Currently, the Google Calendar service only allows users to toggle between “Light mode” and “Dark mode” in its design settings.
However, it appears that monthly background colors will be introduced in the near future. This possibility was uncovered through our original “App Analysis” content.

Following an analysis of the Android “Google Calendar” app update v2026.26.1-943790361-release, released on Wednesday, July 15, 2026, we confirmed the addition of resource code related to 12 distinct monthly background and button colors. This suggests that Google Calendar may soon feature dynamic, month-specific color schemes.
