I have been invited to a fall wedding where the attire for all guests is “formal - must be maroon or burgundy. Nothing that resembles purple or wine.” This confuses me because to me, wine is burgundy. Would this dress work? If not, can someone please explain the difference??

Any other deutans find burgundy and maroon very easy to distinguish? I hear from some people with normal color vision that the two colors are too similar, and they can’t tell the difference, but to me they look pretty different. Burgundy looks like a significantly more vibrant marron to me, just as different as periwinkle and aqua or even more different looking than olive and brown. I was curious if these colors somehow have more contrast to us?
