Nivochart Calendar color help

I’m trying to use a Nivochart calendar to display the usage of meetingrooms (Either by Minutes or Hours pr day)

So far so good. Min is 0, max is 8

Any value above 8 is dark orange - which is great. but 0 is teal, evidently the same color as 1, and darker than 2 which is a light teal.
I haven’t been able to figure out what to feed the parameter -EmptyColor in order to get 0 to just be white.


Duh, just don’t add data for the days with 0 meetings

Still not a fan of some higher values beeing a darker color (0-2 vs 2-4 teal vs light teal).

And boy does this chart not work well on dark theme
