Is an areola that is 3 inches in diameter normal/average for a DD cup size? Plus a question about the coloring.

My breasts are a DD cup size and my areolas are three inches in diameter. Is the diameter normal for my cup size? I've read that areolas range from 1.5 to 4 inches and above, but I feel mine are way out of proportion with my breast size and cannot find information that breaks down the normal diameter by cup size. They take up at least 1/3 of my breast and are unsightly and unattractive! (My husband says 1/4, but neither of us know where to measure from.) They are also too dark for my skin tone. My husband says they are a walnut color, but I think they are darker than what he sees. I see more of a dark butterscotch. I have a light skin tone; I'm fair, but not white as a sheet. I have dark brown hair, and brown eyes. My areolas are much, much too dark for my coloring and are extremely out of place. I am uncomfortable with being naked in front of my husband because they are too dark and too big and out of proportion with the rest of my body! I am extremely uncomfortable with them, and do wish to change them (not by surgical means, so the size is here to stay, unfortunately; my husband is against cosmetic surgery.) They have shown through shirts, even with a bra on if the bra doesn't have a dark fabric or thick fabric element to it; they show through PJ [RS bleep] and cause me to have to wear a bra from the time I wake up till I go to bed. Is the coloring normal for my skin tone? Or is this something that is abnormal and caused by too much melanin  in the body? I get that some men like bigger areolas and darker areolas, and my husband seems to be one of them, but that really isn't the point of the matter, because I have to feel beautiful in my skin, and I do not feel beautiful now. It's not a matter of loving myself or seeing the whole picture (because when a picture is marred by something that takes attention away from the rest of it, the blemish is an issue. If the Mona Lisa were to get a mark on the nose that was so noticeable that it distracted from the rest, she would be fixed.) It's the first thing that is seen, and therefore defines my body, which I see as making the whole unattractive. I can produce a picture if need be, but only though a private avenue and if M.D. is behind your name.
