First apply a clear base coat, I use one from Sally Hanson.
Then apply a hot pink color to the tips. I used Opi's Strawberry Margarita but you can use whatever you have laying around! I did this free-handed, I just took my time and painted the tips (it didn't take more than 20 seconds a nail).
Then apply a light pink shimmery color all over the nail. I used China Glaze's Temptation Carnation. The lighter and sheerer your color is the best this is going to work. You don't want to distort the hot pink too much.
I finished by adding a clear top coat. You can use this technique with any two colors you want! It's a easy way to look summery :)
Forgive the low quality picture, my camera broke and this is off my computer's webcam (aka - not good). I am going to be buying a new camera soon so I can take better quality pictures!
