It was so hard choosing colors that went together that I haven't used before! But I found a good cohesion of colors.
The red/pink is a really old Sephora color that has no name. Orange: Zoya- Thandie (Stunning Collection Summer 2013) I like saying that name out loud because it sounds like you're saying Sandy with a lisp. The Yellow: Jessica- Banana Peel (Gelato Mio Collection Spring 2012). Green: Illimasqua- Smash. Blue: Anise- Island Lover. Lastly, the purple: China Glaze- That's Shore Bright (Sunsational Collection Summer 2013). I cheated with the white base and used OPI- My Boyfriend Scales Walls which I have used a lot, but I only have two whites, and this is the best one!
The way I did this was started with the big dots, and just filled in the spaces with smaller dots. Very simple really. I just wish my freakin top coat didn't drag some of the dots -__-. Here is what I did with my thumb, I might do this as a full manicure someday:
Hope you enjoyed!
