The easy parts are the 'new black, which is spot on to Revell Anthracite, or half way between Humbrol Tank Grey and Black, and the red, which is also a spot on match to Humbrol Satin Red, no132. The buff/ochre colour is a bit more of a problem.
It seems to be close to both Revell and Humbrol Flesh colour, but with a bit of a sandy yellow in the mix to take the pink out. We have 'match potted' our big HMS Victory with a couple of options as shown in the picture of her at Chichester last August. Around the forward gun ports you can see two patches of colour. We have since obtained half a coffee pot of proper Victory paint, but it is not really suitable for model use, being thin and glossy. We will, however do some test shots to see if we can find a decent, off the shelf match, watch this space.
