Yes. And of course that was accounted for when choosing the color and in fact was one of the areas where the turquoise choice clearer outperformed other choices

  They had actually evaluated aqua and purple, and chose aqua because it was more visible? This isn’t critical road information. Why does it need to use the most visible spectrum, and the spectrum closest to blue/green confusion possibilities?

  I’m not sold on their methodologies. They examined one colour, then changed it in the final selection to be more green (which was one of the suggestions). After shifting that original turquoise from the paper into green it’s now in the central neutral point at which the largest groups of colourblind people cannot differentiate it from white, which is the colour used for reversing lights (and also a light in the taillight group). In this paper they should have reviewed the new suggested colour as well; the original turquoise does not have the same confusion with white light, so they’ve effectively taken the pros from a previous result and mixed them into the pros from their hypothetical changed result, without reexamining the new one.
