Unable to null or change dynamic event color

[thekuyaj]

I have installed the module and looking to change the dynamicEventColor from purple shades.
Can you tell me if I am incorrectly inputting it into the config.js section:

Tying to null the color:
{ module: "MMM-CalendarExtMinimonth", position: "top_left", defaults: { calendars: ["Family Calendar"], dynamicEventColor: null, source: "CALEXT2" }, },

Trying to change the color to blue:
{ module: "MMM-CalendarExtMinimonth", position: "top_left", defaults: { calendars: ["Family Calendar"], dynamicEventColor: ["#00009", "#00009"], source: "CALEXT2" }, },
