When you create the instances (blue, red, etc.) store them in a hashtable.

SomeObject blue = new SomeObject();
ht.put("blue", blue);

then:

public void callUse(String color) {
  SomeObject o = ht.get(color);
  o.use();
}

If your instances aren't of the same type, then define an Interface (for
example they all have a method called "use") and use that instead of
SomeObject.
