I understand the actual knob on a breast for a feeding purpose . Wouldn’t just that be enough ? Why the areola around it especially with a different shade of colour to the rest of the breast ?

My wife has explained this to me. A newborn’s vision is incredibly limited so areolas exist to help them find the nipple to nurse. Dark skin on lighter skin is easier for them to see. This is also why some areolas will darken during pregnancy.
