Starting off with neutrals, you'll never go wrong wearing an all-black outfit that has a pop of teal included. Black is a great foil for any bright color and will make you feel more comfortable if you're just starting to wear bolder hues. The same goes for white. Refreshing and visually appealing, white and teal is one color combination that practically screams warm weather. Pair a white sundress with teal sandals, or teal pants with a white blazer for a chic contrast. Gray and teal is also a nice in-between pairing if you're bored of white and black but still want a neutral color.
Another slightly less neutral but still muted pairing is teal and pale pink, specifically dustier shades like rose. A match made in heaven, teal and dusty pink shouldn't work together in theory but somehow do. Though pink isn't a neutral in the same way white, black, and beige are, it can have the same neutralizing effect on a brighter outfit. For example, if you have a dusty pink blouse, a teal jacket would look incredible over the top. Plus, teal and pink complement each other on the color wheel, so it's really only fair to put them together.
