Startup Idea : Make up app for females

Make up is the first thing for every female after she wakes up. I am thinking of an app that, based on a real photo of you without any make up on and the cosmetics sitting in front of you, can give you several options for today's makeup and for every option it can tell you which cosmetic you should use and how to do the makeup. I am not sure whether this is realistic or not but do think it is a good idea as all the makeup apps in the market are just videos from others showing how to.
