Each season brings a specific set of colors with it. For example, fall brings the oranges, browns, yellows, and reds. This is why when people get their colors completed for their best look they are labeled a season, not just a color set. If a person is labeled a the season of Spring, which is pastels that are soft and lovely, chances are they will not look very good in Fall or Winter colors. While most people can wear colors that are incorporated in just about any season, you will see when someone is not wearing the right color for them, as their skin, hair, and eyes do not look complimented, but sickly or drab.
Going back to the Spring example, most people that are considered a Spring do not look good in super white or white-white. Their skin needs to have some yellow or a hint of another shade. This is truer of those skin tones that are green based. Green based skin tones have a beautiful underlying color, but tends to clash badly with stark solid, or bright primary colors. For these types, it is best to avoid yellow based colors. The other skin types are red based and yellow based. While there is the idea that only specific nationalities have specific color bases, the truth is that anyone can have any one of the three tones, regardless of ethnicity or skin color.
Getting your colors done is a great way to find out what colors will work best for you, and to find out what season you are. This will help you make good decisions on the types of outfits that will work with your exact features, making fashion a snap, and all of your friends jealous.
