Source: Franken (mixes of existing polish)
Comments: I was feeling kind of bummed for not picking up FingerPaints Blissfully Blue when I first saw it at Sally Beauty Supply (available in stores only), and I haven't seen it since. To console myself, I figured I'd try frankening my own, and decided to do two versions since I was too lazy to actually look up a picture of the polish at the time. Application of the resulting polishes was much better when I swatched them on tips. It may be that the base coat I used made it more difficult on my actual nail. Anyway, here they are.
I didn't bother keeping track of exact ratios. Just used a metal plate and large tips till I got the color I wanted, then created the color to match in my bottles and re-swatched to check.
