Troubleshooter of Error: Countif with duplicate data in another column

Countif with duplicate data in another column

I need to count ethnicity from one column, but it could be a duplicate patient.
 
Sample Data
 

992014
  Green

86017
  Yellow

37658 
Orange

91816
Orange

71977
Orange

71977
Orange

97012
Red

97012
Red

79286
Red


 
In this example I would need the formula to return 2 Orange instead of 3 orange, because one of  those is a duplicate record.  I used this formula to get the individual number of patients =COUNT(IF(FREQUENCY('[HIV Report.xls]HIV Report'!$B:$B,'[HIV Report.xls]HIV
Report'!$B:$B)>0,1)) and it worked great. 
 
How can I find unique patients when the duplicate criteria is in another column?
