Warning, this combo is going to make you want to go out and buy Teal Crackle, like today. I started with Milani's HD as a base. HD is a silver, what I like to call a flek holo finish. It's kind of got that China Glaze Kaleidoscope look to it.

and now...love....#239 Teal Crackle. I adore the crackle pattern!

and under the Ikea lamp, you can see the bits of holo from under the Teal. Awesome, awesome, awesome!!

So, this color cracked best out of the 4 Kleancolors I tried. I believe the others kind of buckled instead of cracked because of the humidity. I still need to try Green, Purple and Red, but I'm going to have to wait for milder weather first.
Thanks for looking!
