Use the color wheel to create variation in your wardrobe
When looking at the color wheel, it is simple to pair unexpected colors to make an outfit.
Colors that work well together:
Colors next to each other (dark and light hues of same color)
Colors at 90-degree angle to each other (Ex: violet and red-orange)
Complementary colors: violet & mustard;
The two thirds rule: triad composed of three hues that have an equal distance on the color wheel (Ex: combination of blues and yellows )
