Since I know buffy1 is a make up specialist, I will leave to her. I remember from other threads that she is fantastic with this sort of thing.
I also once got explained that with our colouring, the brown eye liner brings out the blue in our eyes more. Seems to work for me as I often get told my eyes are almost glowing blue.

I find if I use the mauvish colour it almost goes to a pink tinge once I rub it in a bit. It's mauve leading to pink without being over pink
