It is to colorblind people. You could use something else of course, just saying...
It's doesn't matter, since the absence or presence of light would still be perceived by colour blind people. It doesn't change how they would drive, as they are already driving with the knowledge of colour blindness in mind when looking at tail lights.
A lot of colorblind people can tell the difference between red-green and white.
They just percieve red-green as the same.
So they lose the visual cue for front-back under the proposed change.
Colorblind person here. If we're talking about limited visibility differentiation of front and back, the color of light is way less noticeable than whether we're looking at headlights or not (based on intensity). There would be no issue telling whether we're looking at a front brake light or a back brake light so long as the front brake light has headlights around it.
