It’s such a good idea that we started thinking why no one has ever thought of it before. That or maybe someone did think about it, but didn’t go past the thinking stage to the actual doing stage. Guess that dude probably cost himself a lot of money.
In any case, Yanko Design’s new Uni-Signal is taking traffic lights and turning them into something that could be of more use, especially to those who are color-blind. So instead of seeing merely colors to determine when to stop or go in a busy intersection, why not put some shapes into it so that those suffering from color blindness won’t have a difficult time determining whether they’re free to go or whether they should stop. In their example, the Uni-Signal incorporates a triangle shape/red color for stop, a circular shape/amber color for stay, and a square shape/green color for go. It’s a great idea, although, we do have one suggestion.
Keeping in with the universal connotations of certain shapes, we suggest that they make the red/stop sign square-shaped, similar to how remote controls have a square sign to connotate stop. As for the yellow/stay sign, that ought to be the triangle - matter of fact, turn it upside down so its similar to the ’yield’ sign, which in essence is pretty much what the yellow light is for - and the green should remain circular because, well, triangle and square have already been accounted for.
