The three view you've used is an artist's impression, so I wouldn't treat it as gospel truth. By 1944, Tigers in Normandy would have used the following colours:
RAL 7028 Dunkelgelb (note that the last of the four Dunkelgelbs, RAL 7028 Ausgabe 1944 didn't come in until October, so you need the earlier one)
RAL 6003 Olivgruen
RAL8017 Rotbraun
Note that the RAL colour chart used during the war does not necessarily translate into the chart used today, so you can't directly read across.
The only source of true colour matches are the original colour chips. You can see them here:

There are also reproductions of the chips in the Chory book and in the AK Real Colours book. (the references are in my thread on Dunkelgelb).
These will give you an idea:

As for paint for airbrushing, Vallejo and Tamiya colours are not very accurate but spray well. The AK Real Colours aren't. The best options are either the new Hataka range or Xtracrylix available through Hannants in UK.
Hope that helps. For what it's worth (and of course it's difficult to tell on a computer screen), the colours you've sprayed look pretty accurate.
