Is there a way to vary the colors?

[PaekHyun]

First of all, thank you for developing the calendar module.
MMM-CalendarExtTimeline and MMM-CalendarExt2
I am using Module.

But various colors depending on the date? Or I want to do it randomly.
Is this method possible?

If possible, what should I do?

It's all CSS - you just need to write some CSS rules that change the colors like you'd like them to have.
