I also love color contact lenses to make my eyes bigger and more sparking. Yet it is hard to tell what color is the most popular color. It is depending on what situation you need to wear the color contact lenses. For example, if you want to wear them for daily work, then I suggest you to choose some color which is similar to your pupil. My pupil is dark brown, so I choose brown color for daily wearing. The more the color is similar to your pupil, then the more natural the eyes look. If you mean to wear them to some party or ball, then I suggest you choose some bold colors, which you like. I love purple, grey, green colors. It depends on your own preference. Hope this helps.
