Remember the good old color wheel? This one?

Today’s outfits use the ‘analogous color’ theory- they combine colors that are next door neighbors on the color wheel. The first two have a common neutral, and then use blues and greens. The last one has variations of blues and purples. If you’re feeling a little more vibrant, you can use the same principle with oranges and pinks, greens and yellows, etc.- whatever looks good on your family.
