Magnetic Lip Coloring

Ever where a lip stick color that you don't like? (I hope you're a woman if you said yes) Well, I've come up with the perfect solution. This is a lipstick of two parts. The first part is the actual colorless lipstick solution. It would be negatively charged and in a liquid form. The desired user would apply it evenly to the lips, as with regular lipstick.

This is where the similarities end. The second part of this unique lip coloring system would the actual color. Small particles of colored powder with a positive charge would then be sprayed close to the lips, thus the positive and negative would attract and create colored lips. If you didn't like it, you'd simply use a more powerful negatively charged magnet to remove the coloring and apply a different one.
