Ok I am going to keep this one as simple as possible, and please know there is always the exception to the rule!! The most important thing I can say is to select colors that you feel confident in, and that also complement your skin and the aesthetic of the studio. If you know a color washes you out, then steer clear, do not buy it! As a general rule of thumb pale skin tones often look good in darker colors, whilst darker skin tones look good in lighter colors, but of course, this can sometimes be quite the opposite! My personal favorites and what I think everyone looks great in are jewel tones, teals, blues, emeralds, and fushia purples.
