Which feature allows you to personalize the appearance of your Google Calendar?

Personalizing the appearance of your Google Calendar primarily involves adjusting the visual elements that enhance your user experience. A background image, when applied, can greatly change the overall aesthetics of your calendar, making it more visually appealing and tailored to your preferences. This feature allows users to set a personal touch, distinguishing their calendar from the default settings and boosting personalization.

While color coding is indeed a feature that allows users to categorize events visually, it relates more to organizing and distinguishing different types of events rather than altering the calendar's overall appearance. Event reminders and task management are functional features that aid in productivity but do not contribute to personalizing the look of the calendar itself. Thus, choosing a background image stands out as the primary method for personalizing the visual aspects of your Google Calendar.
