Tie Dye Nails: Get a bowl of water Pour little bits of all the different shades you want (it should float on the top) Swirl with a toothpick, (Until it looks how you want) Then dip your nails through the water.
Acid Wash =) Paint your nails with a blue color. Apply coat of blue. Apply a white color on top. Dip a Q-tip in nail polish remover & gently swipe away the white. Be careful not to get to your bare nail.
Beautiful ombre technique (Ombre is NOT where each nail is a different color. That is a mono-chromatic color palette, like you would find on a chip from a paint store. Ombre is a gradient from one color to another.
