Calendar Palette Pro is a Chrome add-on designed to enhance the Google Calendar experience by allowing users to add custom colors to their events. This tool provides a simple color picker and hex input, enabling users to go beyond the default color palette offered by Google. With this extension, you can easily personalize your calendar events to better organize and visually differentiate your tasks.

The functionality includes the ability to save frequently used colors, apply them to individual events, or to all events with the same title. Additionally, Calendar Palette Pro ensures that event text remains readable against both dark and bright colors, improving accessibility. However, it is important to note that this add-on only works with the desktop version of Google Calendar, while the mobile version retains the native color options.
