Categories list with color in calendar view

Hello

I have created a menu item of the type Calendar.

I have different categories, each with a different color. Now all events in the monthly view calendar are displayed with their category-color.
Works perfect!

Now it would be important to show a list with all categories and their color underneath or on top of the calendar. This is for "explanation" for the visitors.

Please have a look at the screenshot (just a quick example):



The name of the categories themselves should be linked to the category view.

Is there a setting to activate this list?

Thank you very much!
