This kills the theory that the ancients didn’t see the color blue.
Since that wasn't the theory, no it doesn't.
Despite all the arguments below, I think the notion that they couldn’t see blue came originally from a phrase in Homer;that was hundreds of years before the destruction of Pompeii, and we don’t know when the ‘blue room’ was painted.
I don’t know if they saw ‘blue’ or not; but my Bolivian friend calls my obviously green eyes ‘azul’...
