Gas Switching Protocols

There are risks to relying on colour coding.

Having said that, my 100% O2 2nd stage is yellow, and that reminds me not to touch it until I get to 20 fsw. It shines white at depths where yellow does not glow. And also in the dark when my cave light shines upon it.

Other than that, I would avoid colour coding schemes.

as I mentioned my color coding scheme is set up as a handy way for quickly identifying tanks on the surface when I'm filling, setting up gear etc.

As it is there, I'll use it as a second check just so that I know if it is not what I expect that I should check again that I deployed the correct reg. not something to rely on.

If you have a brain fart or your mind is otherwise occupied when you are setting up your gear and accidentally put the wrong colored reg on the wrong bottle, you'll introduce major confusion at depth.

Personally, the 'keep it simple' method of labeling analyzed contents and reading the label is preferable.

I have a yellow second stage. It goes on 21%, 32% stages, trimix stages and bailout bottles. Why you may ask? Because that is how I bought it, a second stage with a colour.

Colours change under water, location of bottles can change during a dive (think about an emergency or change of plans).

The only safe way to assess what you are breathing is reading a label on a bottle you tested and wrote that label on........
