Black is the darkest colour there is due to its complete absence of light, but it doesn’t always have to be thought of as scary or sinister. Dark, or black-coloured contact lenses can give you a very sexy and seductive look. Black is also considered very elegant and sophisticated. Black coloured eyes do not exist in nature, people that appear to have black eyes really only have very, very dark brown eyes, but regardless, you can feel yourself looking deeply into them anyway!
