That depends on whether you want to change your eye color or just enhance your natural eye color. If you want people notice your eye color, you can choose warm colors for your contacts, such as brown since you have dark eye color. If you just want to enhance your natural eye color, you can choose contact lenses in Hazel or 3 Tone Brown Color to match your dark eyes.
When you choose the right colored contact lenses, the most important thing is that they make you feel comfortable and attractive. I would highly recommend brown colored contact lenses which will make your eyes look natural and outstanding.
The right color of contacts that will suit you mainly depends on many factors such as your skin tone and hair color or style. Most importantly, it dramatically depends on what kind of look you would like to achieve, for example, subtle and natural-looking or dramatic and daring. However, because you have dark eye color, opaque colored tints may be the best choice.Moreover, you also can choose lighter honey brown or hazel colored lens to achieve a natural-looking. However, if you want to be out of ordinary,you can try some vivid color lenses such as blue, green or violet.
