My favorite color is silver. Second to that is gray. I have a gray house, with gray walls, gray clothes and a gray cat and I used to live in a gray city where I drank a lot of Eary Grey tea. Now I even have a few gray hairs.
I love painting my toes gray or silver; my favorite gray is Essie Chinchilly and my favorite silver is OPI Birthday Babe. One man I used to hang out with thought silver nails were tacky, so I always chose another color if I thought I might be exposing my toes in his presence just to save myself the grief of his criticism. Personally, I think silver looks elegant. More important it goes with everything and I do not have time in my busy schedule to change my polish color to match my outfit.
