i think royal wink looks good with almost any eye combo. you could use it as a top liner that will go with browns, pinks, greens, blues of course etc etc
i find myself using it a lot as a lower lash liner though in a contrasting way. like orange shadows on top and then royal wink on the bottom. or pinks on the top and rw on the bottom etc etc.
if anything it also makes a good base for your blue shadows like deep truth and such.
or for just a simple look, nude shadows or a simple wash with royal wink to line for a pop of color.
