Hi @Tara Coia
To create color coded events in SharePoint calendar, You could follow the steps below:
1.Go to List Settings, and click the Category column and create your calendar category values
2.Create a custom calendar view for each event category. In Calendar tab, go to List Settings, find the list of actual views, click Create a view > Start from an existing view > Calendar.
In the filter section of the view, configure it to show items only when "Category" is equal to "Whatever you put for your category” and click Save. You’ll need to create a view for each category you want to color code.
3.Create a blank calendar view to overlay your categories views on its basis. Alternatively, you can modify a default SharePoint calendar instead, set the filter to only show items when "Category" is equal to...and leave the field blank. When you save the view, you should see an empty calendar, assuming you have a category assigned to all the events.
4.Open the view you created last and set up as default, click Calendar tab and then click Calendar overlays, click New calendar, give your calendar overlay a name (to avoid any confusion, consider naming this to match the name of the category). Select the color and click Resolve button so that the other dropdowns populate with your newly created list views. Repeat this for each category (up to 10 overlays total per calendar).
