I think this is a request, but one feature I would like is the ability to configure conditions formatting based on rules. This is something available in miCal and Outlook and I have found super useful.
For example, I might have a rule that if a task has a certain tag that the color of the text be blue.
Or if a task is after a certain time in the day that it is grey, until that time comes.
This would add another level of value beyond what native Reminders has.
