Patient ID or collor coding

In Medisoft there is color coding option, and we can pick color for patients, like we pick color for facility in Open EMR. I have three facilities, and I want to pick color for patients same like facility color, and from the list of patients, I can sort patients by color. This actually very good option in Medisoft.
In EMR we can only color option in calendar, for pickup tipe of visit. But I need same future in patients list. 

or

Is there is a way to have different patient ID options for different facilities. If I have 3 facilities, for the first patients ID starts with letter A, like A298, for second B341 and third C111
