Thanks for pointing out that the color thing is simply a joke and that it is not required that anyone wear any particular color. People reading about DIR for the first time in this thread might think that this is actually a serious requirement, which of course would be silly (I'm liking this word today).SparticleBrane:As I understand it, the "all black" thing is mainly an internet joke. I believe that red has been used in the WKPP for a long time due to filming purposes but don't quote me on that.
Personally I prefer all black dive equipment. I think it looks nice, doesn't fade too much, and isn't distracting like other colors (read: neon pink). If other people want to wear colors, go for it.
