        I’m not colorblind and see 74, but I can see how it can be read as 21. The bottom part of 2 is a less saturated orange.

          Absolutely. I can’t drive a train because of possible confusion between red and green signals but where I live the tram signals just use white bulbs.

            Same here, about tram. I don’t have problem about red and green lights. Or with colors when I wiring something. Just, I missed few points on eye test if I’m able to drive trains, tram and passed eye test that I can work on railway
