I can only endorse blue nail polish if it is sparkly blue. (I also don't do fingernails, ever, because I notice chips in it immediately and then have to take it all off.) I did, however, have a bottle of a dark chocolatey red called "vixen" for awhile there.

My most recent color has been sparkly purple, sometimes with dots of milky lavender painted on top. Not that I ever don't wear socks, this season. But I secretly have painted toenails.
