We are going to create a new view, so click Create a view > Start from an existing view > Calendar. Give a name to your new view after the relevant event category. Add a filter to show the calendar items when the Category column is equal to your category value. Save the view. Repeat the process for each category.

  3. Create a blank calendar view to overlay your categories views on its basis. Alternatively, you can modify a default SharePoint calendar instead. Set up a view filter the same way as earlier but leave the category field empty: Category – is equal to – “blank”. Give a name to the view that would indicate the all-views-in-one mode and set the view as default.

    var sep = “|||”;
    function ColorCodeCalendar() {
        var bodyContainer = jQuery(‘#s4-bodyContainer’);
        var q = ‘a:contains(‘ + sep + ‘)’;
        if (bodyContainer.find(q).length > 0) {
            bodyContainer.find(q).each(function (i) {
                var div = jQuery(this).parents(‘div[title]’);
                var colors = GetColorCodeFromCategory(GetCategory(this.innerHTML));
                var anchor = jQuery(this);
                div.attr(“title”, GetText(box.attr(“title”)));
                div.css(‘background-color’, colors[0]);
                div.css(‘display’, ‘block’);
                if (shouldcolortext) {
                    div.find(‘div, a’).css(“cssText”, “color: ” + colors[1] + ” !important;”);
        window.setTimeout(ColorCodeCalendar, 2000);
    function GetText(originalText) {
        var parts = originalText.split(SEPARATOR);
        return parts[0] + parts[2];
    function GetCategory(originalText) {
        var parts = originalText.split(SEPARATOR);
        return parts[1];
    function GetColorCodeFromCategory(category) {

        var fg = null;
        switch (category.trim()) {

    Color Coding Office 365 Calendar with Virto App

    The Virto Calendar extends the native SharePoint calendars functions with the ability to overlay more than 10 calendars in one view, and lets users easily adjust calendar categories colors.

    View the video guide on how to color code an O365 calendar.

    Step1. If you have already color coded your calendar, you will see a dropdown color legend on the Calendar upper right part. These colors are for the ones you have on your calendar. Now let’s suppose we do not have a color legend for another calendar, and we want to have one.

    Step 2. We will go to the settings and find Available data source to edit. When we scroll down on our data source settings, we will notice Select field for color coding events. Then we click on it and choose Category. Now we are given a color legend. Here we can designate our own color numbers, or we can choose from the available ones. After choosing it, we scroll down and save it.

    Step 3. Now if we go back to our calendar and click on the eye icon to view, we will see that our data source has a color legend now. So, we can see a lot of different colors on the screen, and now we are able to change the color legend inside of the data source settings. However, there is also an easier way to do that.

    Step 4. If we go to a particular event and click on Edit, we will see an option Change category. If we change the category and save it, we will see that the color of that specific event has changed.
