Thanks all, much appreciated
The red is actually really simple. Its just 3 stages. GW scab red, then 50/50 with blood red, then pure blood red. Of course, now that they've changed all their paints, I have no idea what the equivalents will be, I'm just hoping I can get enough done before I run out!
They're all packed up and ready for tomorrow, all I need now is to miraculously remember all the rules!
