Let's set the accent bar of a date.

Step 1: After you log in, click on Calendars (brown box below).

The Your Calendars page will open.

Step 2: Choose the calendar you wish to modify (brown box below).

Step 3: Click on Design (brown box below).

Step 4: Scroll down and click on Days and Dates (brown box below).

Step 5: Scroll down until you find the headers Current day accent and Selected day accent.

Ah.... here we go...

Current day accent: This is the date it is today on your calendar. As I am writing this, it is September 8. So, the current day is September 8. Thus, the accent (the thick red line at the top of the date square, blue arrow below) is on September 8.

Selected day accent: Perhaps, though, I want to look at another date to check which events are (or were) on that date. In this case, I click on the date I want. Let's say I wanted to check what happened on September 3. Here is what happens after I click on September 3.

As you can see, there is now a thin blue line above September 3 (the date I chose). It is blue because I chose blue with the custom color picker (more about that soon).

Note that the options are the same for both design items: Default + Custom.

Current day accent: The default depends on the EventOn Theme. At the moment, it is hardcoded to light red as in the image above.

Selected day accent: The default depends on the EventOn Theme. At the moment, it is hardcoded to mid grey as in the image above.

Click on Custom and then click on the circle to choose your color.

Here is a walkthrough of this option.

Click Save at the bottom of the column to save your changes.
