I like pairing this liner with purple shadow, but usually I just wear this one alone for a bold color on my lower lashline. If you want to use Ola Viola with shadows, I suggest doing a purple smokey eye and then smudging the kohl on your upper and lower lashline. Its a very light eyeliner so I like to intensify the color with a bolder purple shadow like Leisuretime.
Some purple e/s you could use with Ola Viola are: Leisuretime, Digit, Li'lily, Beautiful Iris, and Creme de Violet.
