Antoni is right there Karl. The early colour, which you won't be using, WAS a very pale pink; as I mentioned, an off-white, the 'off' being pink. At that time, there was also a very short-lived, experimental, very pale green colour tried, on only two airframes, AFAIK. The colour shown on the very nice model you posted, if ever so slightly lighter, would be more like this earlier colour.
The B&W pics in Price's book, make the pink look lighter than it actually was, possibly through overexposure of the original film negative, whereas the colour shots that appeared on the rear dust jacket of the first edition of the book, although, as Antoni pointed out, suffering from slight fading, and probably degradation of the colour couplers and dyes, is closer to the actual colour.
Cutting a very long story short, when I was still with the 'Big Yellow Box', I analysed these images, and found that the half-tone reproductions of the B&W pics were a little lacking in their dot-percentage range, resulting in a slight loss of contrast across the full range of tones. A similar exercise with the colour pics showed that they were probably from transparencies, and that, although possibly overexposed, and showing evidence of slight fading, the colour reproduction had not suffered too much. In other words, the colour shots were reasonably close to the actual colour tones. This was confirmed by a then neighbour, who had served as an armourer on the Squadron, at the time the pics were taken at Melsbroek, Belgium.
If you haven't got the colour shots in your copy of the book, let me know, and I'll scan and send them.
If you base the finish somewhere between the original pics, and that shown on the restored aircraft, you shouldn't be far wrong.
