The artwork shows a complicated four colour scheme (presumably the type mentioned here). I freely admit to finding these  types of schemes – to the extent that I have tried them – difficult! It doesn’t help that the suggested colours do not appear to be the same as the colours in the image. So, I decided to wimp out for a model of this scale and following the quote in the Wikipedia reference (“In late 1916, the Solomon scheme was abandoned and tanks were painted with a single shade of dark brown.“) I went with the below colours.

Primer: Tamiya “Fine Surface Primer” (white) spray can

Base coat (tank and grenade screen): A mixture of 90% Tamiya acrylics (XF-49 “Khaki” (80%) and XF-57 “Buff” (20%)) and 10% Tamiya X 22 Clear in Tamiya X-20A thinner (2:1 paint mixture to thinner).

Base coat (steering tail):  A mixture of 90% Tamiya XF-63 “German Grey” and 10% Tamiya X-22 Clear in Tamiya X-20A thinner (2:1 paint mixture to thinner).

Details:

• Machine guns: Vallejo Model Color “Black” 70950
• Front lights: Games Workshop “Mithril Silver”
• Tracks: Vallejo Panzer Aces “Track Primer” 304

The paint was protected with a layer of Humbrol Clear gloss varnish and then Citadel Purity Seal satin varnish.
