If you are applying both blush and under-cheekbone contour, apply the contour color first and then blend the blush on top of and gradually down into the contour color. Then, using your sponge, blend until you meld the colors together into an attractive design. The hallmark of an attractive design is not being able to see where one color stops and the other starts. When done properly, blush and contour add color, depth, and dimension to a face—and that’s always attractive.
