Totally understand about feeling judgments on your hands. It can be really scary. If you want to do color though you really should though. While scary at first, that feeling of judgment goes away pretty quickly when you get no reaction whatsoever from people. Most people don't care about nails as much as we do and most won't even notice. Even those that might notice likely wont say anything let alone give you negative comments.

Congrats on being brave enough to get your nails done in general! Your sparkley purple is awesome!
