Ever seen someone who takes "matching" to a whole new level? [e.g. ~ a brown suit and red shoes, red necklace, red ring, red belt, red purse, red lipstick, and red stockings]. This is someone who may have missed the beauty of hueing ~ using a gradation or variety of a color.
Style note: "matching" can add to the overall frustration of dressing while, hueing allows much more flexibility in coordinating looks!
