The auto selected colour for the event details (tags, venue etc) fonts does not meet colour contrast standards and there is currently no option to style the font other than selecting the font size. Allowing the user to select the font colour would mean we could select a colour combination from our brand that meets requirements.
Hello there, @tfilippi 
I am glad to say that you can change the color of the event elements like venue event type, date, time, etc right in the settings. To find these options click on the Customize Theme button on the Theme tab and open the Event section:
At the moment, there is no separate setting for changing the tag color, but you can achive this using the CSS code. Just add the code below to the Custom CSS field on the Settings tab of your widget’s settings:
.eapp-events-calendar-tags-item {
color: green!important;
}
Check it out and let me know if it helped
