Teal, which I have professed my love for many times, used to bug the crap out of me. I avoided it. The fact that stuck in my craw the most was that if you bought five things that were all labeled teal, none of them would be the same shade. In the outfit below, I found shoes, a skirt, and a blouse that were all called teal. Those shoes may not match that skirt, but with the top and a dark blue belt, it all looks thematic. For variety, I added jewelry in a completely different color.
Many people struggle with wearing black and brown together, or with mixing red and pink. Likewise, adding a third shade makes it work. Cream and grey are your secret weapons for befriending black and brown.
Here I have a deep cherry, tomato and bright pink living in harmony. Take out any one piece, and the look clashes.
Likewise, the orange dress and green scarf are an odd combination, but the mustard shoes and brown jacket bring everything together.
