My synesthesia involves seeing certain colors that go with certain odors: earth, sweaty feet, wet dogs, and cooking beans smell brown, regardless of what color they really are; oily things like butter, Crisco, car grease, and so on smell yellow; fruity things and perfumes smell pink; but when my husband became borderline diabetic his smell darkened from brown to an ashen grayish grayish black. It's like seeing a translucent film over the world, kind of like looking through sunglasses -- I see the color, but I still the real colors of things at the same time. Diana Gainer
