After much rubbing down, airbrushing different paint mixes, and getting completely the wrong base colour, I decided to do a bit of research.
First stop was to find out what colour an early Tiger would actually have been painted. Well, at the beginning of the war, or at least around 1943, they really only used one base colour, and that was Dunkelgelb. That colour, according to all of the colour charts that give you the cross-references between paint colours, was Vallejo Middlestone. 882. The disruptive camouflage was dark green, and I have the colour for that too.
Just to check I went on the web and started looking for pics of the real thing and models. This is where the fun starts, as different camera's accentuate different colours and in many cases change the colour completely. We the have the monitor variations etc, as well as the fact that because paint was supplied, and applied, there is pretty much no accurate depiction of camo anywhere. Looking at the sites that claim to show German WW2 camo, there seem to be more camo patterns than there were Tigers built. Most of them are simply artistic impressions that 'look nice'. There is no way that a German tank crew in the midst of battle is going to paint their tank in some complicated camo scheme that would have done the ceiling of the Cistine Chapel proud.
So looking at models I came across these:

I also looked at the Bovington tanks, and again different pics taken by different people with different camera's, show the same tank in a variety of different colours. The one photo I found in natural daylight indeed shows the base colour as a sand yellow/green.

So, Vallejo Middlestone was duly applied. This is RAL7028. I let it dry as it changes colour over 24 hours, and sure enough it is a sand yellow/green colour. Again, when I take a pic in natural daylight, on a windowsill, it doesn't appear that colour at all, it appears to be a tan colour, which is what some of the models look like. The actual colour of this Tiger is closer to the KT above, which is what it should be. It just goes to show that when someone says that the camera never lies, they have obviously never painted a model tank!

So I reckon I am on the right track.
