Is it possible to filter the selection from Core Data from duplicates using NSPredicate?

Question

Objective-C

Core Data contains objects one of whose attributes is not unique.
For example:
object1.color = red;
object2.color = green;
object3.color=blue;
object4.color=green;
object5.color=red;
object5.color=pink;
I want to compose an NSPredicate in an NSFetchedResultsController so that it returns a list of colors to me. It is important that the colors do not repeat.
What I want to get:
Colors:
Red
Green
Blue
Pink
Is it possible to do this with NSPredicate? If not, how can I arrange this in NSFetchedResultsController?
