complementary is using two colors that are directly across from each other on the color wheel. I decided to use red and green and create a Christmas outfit. I chose the green sweater because sweaters are perfect for winter weather. I chose the pants because i thought they went well with the sweater and they have both red and green in them already. I chose these shoes because I love when winter outfits are styled with boots. Lastly i just chose a simply black purse.
