Drip Bottle colour preference?

[RKayne]

I am curious as to your preferences as to your drip bottles colour. It is nice to be able to see the level but you can shake it and tell. Is it not better to use a dark colour? I ask mostly because I can get a really good deal on about 200 or so black 3 ML drip bottles and could share the wealth by making smaller packs for cheap. And I mean CHEAP

I just found out I can get clear and white as well...
