How to change conditional formatting schedule background color all at once from dynamo

Trying to change color from dynamo .
All schedule at once.
I have 30 schedule.

Anybody can help me out from dynamo script

Looking at this thread, it doesn’t appear that Revit API is able to do conditional formatting yet. If Revit API is not capable of it, neither is Dynamo. And looking thru the API, I also couldn’t find anything useful. So for now, it is not possible.
