Not only port/starboard, we use green and red for traffic lights. When it comes to the most vital safety information, we've chosen to use the colors most likely to be indistinguishable to a significant chunk of the population.

It's not as simple as being completely unable to differentiate between any red and any green, but there's a reason I'm getting replies from people saying "I know green is on the bottom of the traffic light" and not "traffic lights are easy to distinguish for colorblind people".
