Well I'm going to go read my book "The Longest Winter" by Alex Kershaw. About I and R platoon. 18 men defending a valuable hill in Lanzerath (Proper spelling?) , Belgium and found themselves against the spearhead of a German attack of more than 500 soldiers. Have a nice night and a good day if I don't talk to you tomorrow!
The red should be fine, you can always add a drop of the dark earth (brown) to that and the effect will be the dull red.
The grey , look at the profile, you will know.But it will be needed at the finish.
Do you mean the dull red? If yes you don't need to get it.It will be enough if you mix the red and dark borwn. About the mixture ratio we will talk later.
