Random Color Generator - question!

Thanks for this tutorial, its great! I only have a tiny problem: I want the squares to start white and not black. How can I do that? Ive looked deeply at the codes and tryed changing some stuff - but nothing works for me. It is really important for the website Im designing that the squares will be white at the beggining and not black.
any ideas?

thanks!!
