1. Do I apply my blush only on the apples of my cheeks and going outwards where exactly? What colour should my blush be?

2. So even my bronzer do I also apply on the apples of my cheeks or just forehead, bridge of nose, chin where the sun naturally hit

I like to use bronzer as a blush. I’ve heard of a few different way you are supposed to apply it (some say on the cheek bones, some say to underline the apples of your cheeks, etc…..). Which is the right way?
