Celtic Moment

Hey, I’m thinking of putting together a massive LARP battle over the summer (It’s fun as all hell, Try it), Of which I will be the commander of one side.
Among my friends, I’ve been accepted as the “Viking” guy, under my own devices (I know what “Jöntr” means, that’s pretty damn viking), and I’d like to use that to my advantage, by using Viking War Runes in dressing up for the event. I know of at least one, the Aegishjalmur, but I’d like more options. I’m also aware of the traditional alphabetical Elder Runes, and I’ve heard they have meanings. What would be the proper way to apply these to myself?
Also, what’s the traditional color of the Rune marks? I’d like to keep it in tradition, Just to honor the forefathers, Ya know?
I’d also like to know if the Vikings wore Warpaint like the Celts did. And if so, in what patterns and color?
Thanks for the help, guys. I know this is pretty abstract, so I’m not hoping for miracles.
NOTE: I posted this in the “folklore” section before, but I don’t think that was the right place to post this. I deleted it and posted here, for better hopes of help.
