As for the water turning clockwise or anti clockwise, it is a common myth that the flushing water follows the same path that athmospheric depressions, hence anti-clockwise on the northern hemisphere, and clockwise down under.
However, while this is true for depressions - due to Coriolis forces caused by Earth rotation - this is not true for flushing water. Although the Coriolis forces impact on the flushing water, their effect is negligeable in respect to other parameters. Even a slight irregularity on your sink will have more effect !!!
Theorically, it could be true only in a perfect environment with a perfecty circular sink. Since my toilet is not like that, I would have to say... it is random.
As for the colour, it is currently blue coloured. I have to change the thingy quite soon though. And it is not the same blue as in aircraft.

Quoting 707CMF (Reply 12): due to Coriolis forces caused by Earth rotation
damnit! you beat me to the coriolis effect! i learned about it a couple years ago when i had this exact FST question boiling in my mind for a few days. i couldn't take it anymore and broke down and researched the topic
