Color has a huge impact on clothes. The color of a garment can change the vibe it gives completely. If you're looking to craft a "look" that projects something specific, this hand color guide could really help.
Of course, these colors in it of themselves won't carry you're entire outfit. But if you're putting effort into what you're choosing, being specific with color can really top it off. For example, ____ might not give off a passionate vibe by itself, but if you add accessories with the vibe in mind (passionate = dramatic floor length dress, dress split, retro wide brimmed hat, smoky makeup, etc.) it's best that they are this color in order for the outfit to reach it's potential.
You obviously don't have to do this, but it really helps if you feel a little lost. It's pretty comprehensive, so you'll probably find your favorite color in here.
