I've always wanted to know what the exact color names of coasters at KI and at other parks are. Is Diamondback red or technically maroon? Is Banshee magenta, purple, or an off red? Is Fury 325's blue the same blue that's on Leviathan. You get the point

I think I've heard Banshee's color as mystic red (which...it's magenta). 

EDIT: I feel safe in saying that Bat's previous color scheme was that of primer because that's what it looked like before the orange. 

You are correct, Banshee's official track color is Mystic Red. I believe that in it's previous life, The Bat's track color was known as gunmetal grey (that sounds right, but I'm not completely sure).

Magnum is not actually red, but molly orange.
