I am all miserable again.
O ordered the humbrol paints as listed earlier in this thread and in other places in MLU.
I mixed them up using measure then using weight.
The green pre 1942 is reminiscent of the colour on the Vickers Mk IV B so I think that is OK but its very dark.
Both the Stuart and the FGT are clearly not that colour. But the mix for the post 1942 green is way too dark. I have some places in the FGT that are pristine ( the lockers in the back and places like that ) and on the Stuart under some of the fittings I have unbolted.
Both the FGT and the Stuart seem to be the same base green colour though the Stuart even when rubbed back is clearly faded tending to whiten off .
The Vietnam era green is closer than the mix of humbrol paints I made for the post 1942 green. So now I guess I have to do a colour match on the pristine parts of the FGT...so I will remove a door and see if I can get a formula for that colour and use that as my base green for both vehicles.
Mikes formula for the light stone is crisper than the colour on the tank but it seems about right given the Tank has faded. I am happy to go with it... I think
Trouble is of all the events I have been to and all the museums visited I have never seen tanks painted in the schemes I will use I have only seen old B&W photos ... maybe I will paint up a model or something but it seems they will they look quite startling.
