Dave,
Many people are color blind red/green (me included). I can tell the difference but it is not huge. I'm sure some people can't tell the difference.
Rick,
The Meg has a flash code. Basicly, green is above 1.0 and red is below 1.0, amber is 1.0. So 1.3 looks like blink, blink, blink, pause, blink, blink, blink, pause, blink, blink, blink, long pause (all blinks are green), then repeats. It is looking at each O2 sensor. If your color blind, it looks the same. 0.7 is 3/10ths below 1.0. Being color blind requires extra attention. So when I dive the system, I start at 0.7 at the surface. If my diluent is 10/50 (50% he +an air top off), I pay attention if adding diluent above 20', below, no issues. I watch the HUD on the way down. When hitting the bottom (150 to 200), the system is near 1.0. Here, I change the set point and look at my pressure gauges to ensure (one more time) that the gasses are on. The sytem will now inject O2. On the Meg, it is a 2 second on followed by 8 seconds off, repeated until O2 is above set point. So here I listen for the next minute and when it stops the firing cycle, I look at the hand set (1.3) to ensure all sensors are healthy. At this point, I look at the HUD every 45 to 60 seconds for just a single blink, blink, blink. Every 5 min., I look at the hand sets for real numbers. On the ascent, I pay very close attention, this is when most problems happen due to reduced pressure. I'm not stating that my way is best, just that I have a system and won't be complacent on a RB. This is another reason I chose the Meg, it is not automatic - you have to fly it!
