Well nothing on a computer is completely random. There are algorithms to create near random integers, but they are of course not completely random and thus you end up with problems like this. although it is only 2 numbers so there is a chance you could get a 7 in a row streak.
Another problem is a lot of people will abort until they get white so... yeah
Anyone else here of issues with the random selection with color for bullet chess? I've had it where I would be given black pieces literally 7 times in a row or more. That doesn't seem like a random selection. Anyone else run into this?
