My code currently updates the colors of shapes (rm) if the current hour and minute matches a field in the txt file. My problem is that I need the shapes to stay that assigned color until it is overwritten by a new matching field in the txt file. 

Also, I only need to check if the fields match at hh:00 or hh:30, so I feel like draw() should only be called when the current time is either of those times. But then the clock doesn't run continuously...

Let me know if this isn't clear!! Thank you!!
