Make a Schedule plan for Holidays, and Joint Leave with different colors

I want the Schedule to have several different color variations as per the National Calendar reference like this

  • Working Day: White
  • Work Holiday: Red
  • National Holiday: Pink
  • Leave: Green (Leave that has been submitted and approved)
  • Joint Leave: Blue (Because Joint Leave can still be entered)

So how do I make the schedule more colorful?

Why don’t you set up a Joint Leave entitlement?
