Dark-coloured eyeliners such as navy blue, brown, indigo, or deep green will define your eyes and add some colour; they are a good alternative to black for a daytime look.
While bright baby blue, green, aqua, violet, or bronze are great when you need bright colour on your eyes, quickly and precisely applied in a line. Choose a colour that corresponds with your attire. Eyeliner with shimmer will add a subtle shine to your eyes – very sexy.
