When you want your shoes to blend in, to give you an overall head-to-toe refined look, choose shades and tints based on the color of your dress. These will look like they match beautifully.
When you need to purchase shoes that will go with the widest range of your wardrobe, choose a neutral color. Select a variant of white or light tan if your dress colors tend to cluster towards the center of the wheel. Similarly, if your dress colors tend to cluster towards the rim of the wheel, choose a black shoe for the widest use.
And what about analogous colors? While they may look beautiful when painting, they usually should be avoided when dressing. Shoes chosen from among analogous colors often look like you tried to match, but failed.
You’re ready to rock it! Leverage the color wheel to choose shoe colors that are either complimentary, triads, or shades or tints based on the color of your dress.
