I know this isn't original or anything, I just wanted to do it for myself and thought I'd share it with you guys, too. Sorry I forgot to take a photo of the final design, I put a glitter polish over the hearts. You can see it in the video though, at this link.
So the base color is a light pink by the Color Workshop (no name for the color). I think I did 2 or 3 coats, since you can tell it's very sheer.
Then, I used a regular small paintbrush and acrylic paint for the hearts, purple and silver. Use whatever you like or have, that works for you.
