Has anyone ever noticed highways signs? White letters on green background. The highway administration spent a lot of money in the 1950s to arrive at that decision.



Barry, there was more than strict legibility involved in that choice.
Black on yellow was determined, in those studies, to be the most legible
combination, which is why it is used for safety warning signs. It made
no sense to use that first choice combination for informational signs,
however. Green was a preferred background color because it was thought
that from a highway beautification point of view, green would be the
least annoying color against the natural background. White on green
gives excellent contrast, but so do several other combinations.
