Fish Egg Nails
I used the "fish egg technique", I stole the different color idea from my roommate, she did the same thing with a different color and I loved it. Basically, you can paint your nails any color then while your nail is still wet, dip it into the bottle or pour the beads on top and let it dry. Mine have stayed on pretty well for about 4 days now. If you don't pick at them you should be fine. I bought the microbeads from Michaels.
This was the bottle from Michaels, it came in a six pack with other colors as well.
