I have a SharePoint Leave Request Calendar. I wish to color the events based on approval status. Yellow pending approval, green approved, and either remove event if rejected or show as red. How can I change Display Color using Nintex Workflows

Hi there:
It sounds to me like you might need to go through vanilla SharePoint processes and set all this stuff up:
Color-Code Events on a SharePoint Calendar | PremierPoint Solutions
And then just call the specific category set from your Workflow. Then you'd have to ensure that the category updates from type to type when the status changes.

- http://www.sharepointjunkies.com/color-coded-calendar-sharepoint-online-using-javascript/ (more like your case).
Do you find any from our answers correct? If so, please mark the most helpful as correct so that other users will know this question has a solution
