Re: Re: alternating colors

Your solution would alternate colors one red, one blue, one red, one blue... Rodney was asking for _three_ red, three blue, three red, three blue...which is a little trickier. There might be a simpler function foo(), but I didn't check. For instance, I don't know how % behaves when you give it a number that isn't an integer.
