If you suit Mid Tones you veer towards muted bright colours. Too bright and they overwhelm you; too pastel and they take the colour out your complexion. Your skin might have blue undertones and without make-up you can appear quite washed out. At the other end of the scale, you might have a peaches and cream complexion. Your eyes are predominantly green, aqua or blue.
You look great in purples, especially wisteria and lavender. Soft blues work well, too.
You can sometimes get away with navy, but your best blue is probably periwinkle. Burgundy works well, from plums to more pinkish hues. Warm pastels, like powder pink or blue, are also good. When you are looking at your wardrobe, discard all very cold bright colours, like blue red and cardinal purple, and all colours that are really dirty, like beige or khaki. Your green is a sage (like the fresh, newborn leaf of an olive tree as opposed to its dying neighbour). If you are choosing purple, avoid that bright, cold tone and go for a dark lavender instead.
You will tend to wear similar tones of co-ordinating colours. If you get the colour mix right, they will make you look more alive and you will begin to see a difference. People will start to comment on how well you look and notice the colour of your eyes for the first time. But, most importantly, your wardrobe will be free of those annoying items that don't go with anything else. You will save money, you'll look great and you will no longer have to agonise over what to wear.
