As you can tell by my avatar pic, I've got colored tanks.
Do I prefer colored tanks? No..... If not, then why do I have them? Because I got them for a STEAL of a DEAL.
If I could pick up a tank in hydro and visual for $10 bucks and it was
PINK, then I would buy it. I'd prob dive it also. Yeah you'd get smartass jokes, but just tell them you only paid $10 bucks for the tank and ask if they would like to buy it, most would say yes. If you don't like the color, you can always strip the tanks. (see my "
Recent Stripper Pics"
thread).
Now as for your candy red tank you were interested in, should you get it? sure... should you pay more for it? I'd say no. As you dive the tank and pick it up and set it down, it's going to chip the paint some. Putting it in and out of car trunks, boat racks, fill tnaks, etc it will get scratched. People just don't "baby" tanks to keep from scratching them. So chances are a scratch on your fancy paint job will be worse than on a normal paint job. (in your mind that is)...
Now... the advantages of some color tanks.
1.) You can tell easier who other folks are on your dive if diving in a group and one of your buddies has a color tank.
2.) Bright yellow or bright green are more visable at distances than a diver wearing a black wetsuit and black BC. Someone was diving one of my tanks in the bottom of the quarry at 45' and you couldn't see them. But you could see the tank from the surface looking straight down.
3.) It's different.
