COLOR SETUP IN CALENDAR BASED ON TASK CATEGORY

In the calendar view, I want to set different colors for tasks based on the category.

For example,  if the task category is CALL I want to assign it the yellow color, if the task category is MEETING I want to assign it the Green color ss shown in the image below.

The OOTB functionality says that the colour will change based on the status of task. How can I do the same based on the Category?

I have done this by changing the css of the perticular element just to show an example.
