True. But since the lights are used after dark, there is no practical alternative other than a colored light. I cannot say for sure but color blindness would probably make it difficult to get a Captain's License.Running lights never took into consideration red/green color blindness.
Since you already stated that you have your ear plugs custom colored red for right, can we assume you are not color blind?
It is also worth noting that channel markers are color coded red and green as well. Outward bound the right(starboard) channel marker is green, the left(port) channel marker is red.
However, channel markers also have designated shapes.
The Red marker is shaped like a triangle.
The Green marker is square or rectangular.
None of which really matters here. Finding a color code or other easy identification mechanism for your custom ear buds is obviously not going to be the same for each of us. We each find what works, then we stay with it.
