It is already difficult enough (for me) to see the different shades of light at depth (i.e. red, green) sometimes.
Personally, I wouldn't want to use light of close shade like red - orange - yellow at depth where the colors are not true anymore.
Just my opinion...
Actually I meant YELLOW=ORANGE which shuld be selcted so it is clearly different from both red and green. If not then another color should be chosen - but wich?
The main piont was RED=Danger, and should only be activated if it really is Danger. Normal operation during predive, dive and deco should never trigger red-light.
This has the disadvantage that people cannot remeber the light-sequnces in red, since that color is not used often. I therefor suggested reducing the no. of light states to a minimum: OFF/ON/BLINK, with RED-blink as life-threatning.
Please note that the sugestion was also to seperate PPO-monitoring from everything else, so one cannot get confused between the two. Ie. set them physically apart.
BTW: I thought the color would be as true on the bottom, because the water-distance is the same (i.e. from HUD to mask), and the surrounding light has faded, which should make them lights even clearer?
