You could use a blue (like navy) mascara, or a purple one like eggplant. I think they still sell some green mascaras somewhere but i couldnt tell you where.
But I agree with the blue eyeliner-I think it'd be kinda cool to wear a bright blue but a navy blue would be pretty as well. Also White
M·A·C's Pro Lash Colour is available in a blue colour and a blue-green or you could order some of the Mixing Medium/Lash and make any colour you like with a pigment.
Look at MAC's powerpoint liners. Buried treasure is a soft black with gold shimmer and forever green is a deep emerald with golden shimmer. They have gorgeous other colors too, and the staying power is unbelieveable.
