Mike Starmers' definitive article British Vehicle Camouflage, 1939-45
Dated 30th APRIL 2019, does include Tamiya Mixes.
Mike is pretty active on the Airfix Tribute Forum RAF Vehicles paint schemes which is full of interesting info.
Jon you are correct, Mike Starmer's article: British Vehicle Camouflage, 1939-1945 amended April 2019
does include Tamiya paint mixes. However, and I want to be careful not to create any misunderstanding here, I was talking about his books:
1. British Army Colours and Disruptive Camouflage in the United Kingdom, France and N.W. Europe, 1936-1945 amended December 2019
2. British Military Camouflage & Colours, Sicily & Italy 1943-1945
3. British Military Camouflage & Colours, Alamen & After 1942-1945
4. British Military Camoulfage & Colours, The Caunter Scheme
I am a great fan of Mike Starmer's research in the field of British Military colours and patterns used during World War II and highly recommend his books. In each book is a sheet of color chips that are not printed, but actual colour chips like the type you would find at a paint store. With each colour chip he indicates the paint he used and, in most cases, it is Humbrol and Revell enamel.
The article you are referring too is an excellent piece of work in which Mike has detailed Tamiya acrylic paint mixes in addition to the enamel paint in his books. And I would venture a guess that Mike considers references he has made to Tamiya acrylic paint a work in progress. For example, in the article Mike indicates S.C.C. 15 Olive Drab can be represented with a mix of Humbrol 150, 159 and 33, or alternative Humbrol 253, 80, 159, 33 and Revell 84. He goes on to say S.C.C. 15 can also be represented with a Tamiya mix of XF81, XF58 and XF71.
When I asked Mike for specific help with a Tamiya acrylic mix that would match S.C.C. 15 he recommended a mix of XF61, XF62 and XF3 and to use Neutral Grey XF53 to lighten the mix. At the time I did not have his books or Neutral Grey, so I used XF66 Light Grey and increased the amount of XF3 and it matched the color chip perfectly.
When I showed Mike what I had done he commented that it was good to see other modelers trying different paint mixes which to me means Tamiya acrylic paint as a substitute for Humbrol and Revell enamel is a work in progress.
