For every eye color, there is a best complimentary eye liner color that goes with it. You do not have to only focus on the common threes: black, brown and violet when there are other hues available in the market.

Brown eyes can pull off any color literally, but if you want to try something new, why not try and use green eyeliner? Not only is it different but it will make your eyes pop more.

But if your eyes are already green, opt for purple or violet liner to create a contrast. If what you want is noticeable accent, use bright purple but if you want to try something less obvious but still a little different, you can apply dark plum.

For those with blue eyes, make use of navy blue eye liner. This effectively makes the white of the eyes look much more solid which adds more depth to the irises. If you still are a little apprehensive about experimenting with a little more colorful eye liner palette but sick of using the three common colors I have mentioned, try to use grey instead. Grey is not only neutral but it is less dark than brown, yet conservative.
