Did you ever consider glitter polish to be nude? It can be! Nude nail polish with sparkly accents are fun without being bright!
Start with your favorite not-too-light nude as your base. Then use a white color to add some fun marbling!
For a fun design, start with a nude color then add a semi-circle of two brighter colors at the base. Black and blue is a winning combo!
Add the colors of the rainbow to your nude mani! Paint the edges of your nails starting with red on your thumb through violet on your pinky!
