As you can see by the sticker on the lid, I got this little gem 75% off at the CVS sale last month.  This is 10 Professional Nail Lacquer in Moonlight.  With the flash, it looks like a muddy, almost gray taupe, but in natural light (below) it has a more yellow undertones, and doesn't enhance the redness of my skin.  Obviously, these pale gray/taupes are on trend right now, but finding one that compliments your skin tone is the challenge. 

This 10 Professional line definitely has a broad spectrum of colors, mostly work safe and basic, but even this little guy allows you to wear a more trendy shade but still be neutral enough for every day.  Have you tried any of these yet?
