if Thomas sent you that, I'll agree with it. He's a good friend as well, and I trust his judgementUpdate:
I've been sent a PDF by a friend of mine who's registered under the name "Thomas Krom" on this website. I have attached it.
Furthermore, I've sent a mail to Peter Davies-Garner (I spelt his name wrong in the original post, Jeez) asking the sources which make mention of a "White Star pink" colour.
Until then, I'm saying that my original assumption wasn't correct and perhaps the Ken Marschall colour would be accurate (though I might add that in some colour photos in the article, it does seem that the colour is buff when there's direct sunlight and pink when it's overcast, it's not as extreme as what I shared though).
