My lips of the day are sheer brown.
L' Oréal Color Riche Stars Secrets 708 Aishwarya Rai
Even though my lips look pinkish, the color of the lipstick is really brown.
I'm not sure if this lipstick is available anymore, it was part of the L' Oréal "Stars Secrets" line which featured actresses and models and this specific lipstick was endorsed by the Indian actress and former Miss World Aishwarya Rai.
This lipstick actually comes closest to my natural lip color (of all the lipsticks I own). I have used a great bit of it and I have two backups in case I run out :-)
