Subject: [Flashcoders] parsing multi-dimensional array

so if I have a multi-dimensional array - how could I break them into their own
array? So if I have:
arr[0] = ["red",0,0];
arr[1] = ["red",1,0];
arr[2] = ["red",2,0];
arr[3] = ["blue",0,0];
arr[4] = ["blue",1,0];
arr[5] = ["blue",2,0];
What I need to do is break red into it's own array and blue into it's own array
- and there could be any number of colors....
