color in processing represents an int-type. so you could as well write:
int cl=color(0,0,0);
it's the way the int is written that makes the magic. the int is made of 32 bits or 4 bytes. each byte can represent values between 0-255, sounds familiar
so in fact color is:
AAAAAAAA RRRRRRRR GGGGGGGG BBBBBBBB
(A=alpha, R=red, ...)
more is here:

dividing the int more or less garbles the values since it treats it as one value between Integer.MIN_VALUE and Interger.MAX_VALUE ... maybe a nice way to randomize colors.
