Little blue dot in CalendarEvent / WeeklyView

I implemented a Calendar view where I display multiple calendars, so I want different colors for my calendars.
Basically I managed to get a different color working with my styles. But I hava a small little, blue dot in my Event when I display the weekly or monthly view!

I have no idea how to correctly use a scss selector to change this color! I tried it like this:

.v-calendar-event-googlecal-month::before { color: whitesmoke; } but it didn’t work for me!

Please have a look at my attachment to understand what exactly I mean!

Thanks in advance!


Nevermind. I’m using the more-easy version with .setStylename("[color1 - color5]
