First of all, it's ';which one,'; not ';witch one.'; I realize this is a biology question, but it looks like you should spend some more time studying your English.





Second, this is an unfair question, as it does not provide sufficient data to arrive at a viable answer.





Is the person colorblind? (There's your caveat).
Human eye will respond to wavelengths in air from about 380 to 750 nm.


If looking thro' a denser medium the freq increases by a factor equal to the refractive index of the medium.


So there is no single color.
Red.
