The blue eyeliner is an amazing color for the eyes that many ladies do not take enough advantage of. The black eyeliner in opposition is a safe color that keeps the focus on the eyeshadow, but the blue eyeliner does more to enhance your eyes even while keeping the focus on the entire makeup, so your eyeliner should not be hidden.
The trick to using blue to define your eyes and keeping it in focus is to complementing colors especially with your eye shadow, keeping it demure yet classy. You can however play around with lip stains or lipsticks to give a wow effect.
