I'm sorry to hear about your test, but don't give up on flying. Look at the FAA route.
For class 3 and 2 medicals you have to recognise the light signals from a control tower at 1000 and 1500 yards - this wil allow you a CPL. For class 1 you need to do a medical flight test at night and give the rotating beacon lights as well as taxiway and runway/treashold lights. You might not have flown at night yet with CVD but they are easy to tell. The FAA guy is a flight examiner/official and not a doctor. They are very fanatical about flying and WANT you to pass.
Australia did not have any requirements for colour vision for CPL, but I'm not sure about now.
Any how I know how you feel, don't get down I'm sure you will be a pilot soon.
