Compiler Error - 'Color' was not declared in this scope

Uh-oh... where is the setup? Even if you don't use the setup, you must do this:

void setup(){
}

Oh right, on the line of c = Color(255,0,0); you need to do this instead:

c = strip.Color(255,0,0);

P.S. I replied 6 minutes after you posted!
