I have blue eyes too and love the smokey look. I have a bit of a twist to it though, not whites and greys.

I use a light pink as a base on my lid and just under my brows. I rustic purple over the top of some of the pink on the lid extending up above the lid line. Lastly, I have a really deep purple I use in the outer crease of my eye lid.

When I say purple, they aren't bright purples, but strong subdued purples.

It's a really nice look and really brightens your eyes.

I hope I've made a tiny bit of sense.
