I'm looking for a mascara that has a hint of blue/navy to it that is worth the price! The one that I loved is no longer available and the Cover Girl mascara I have found just isn't cutting it!
YSL Volume Effet Faux Clis
Leaning more towards Deep Night (6) for the more darker navy blue tone. The Sephora pictures although a nice reference are quite off. YSL's official site is more accurate for photoshop matching the colors (was even better when they actually swiped the product). A little lighter would be Extreme Blue (3).
The Mascara Singulier in Deep Indigo (5) as mentioned above may also work. It looks much darker than the picture. It's a deep Ink Blue color.
tokidoki Punk Lash Mascara is a conditioning mascara that volumizes and lengthens lashes with vibrant pigments. It comes in a beautiful vibrant blue called Baby Rocker that you can find here: http://www.sephora.com/browse/product.jhtml?id=P25
Another mascara that is a little more pricey is YSL's MASCARA SINGULIER Exaggerated Lashes – Dramatic Styling which creates extreme volume, length and curl, and saturates the roots of your lashes like the stroke of eyeliner, without any clumping. It comes in Indigo which is a very dark blue and you can read all about it at: http://sephora.com/browse/product.jhtml?id=P247505
One tip that I wanted to let you know about to get the most color payoff from the blue (or any colored) mascara is to apply a white eyelash primer before applying the mascara. Giving your lashes a white base coat will make the blue really stand out when applied over the white. And be sure to let the white eyelash primer dry completely before applying your blue mascara. A good eyelash primer to use would be Urban Decay's Eyelash Primer Potion which you can find here: http://www.sephora.com/browse/product.jhtml?id=P24
I hope this helps you.
