This is 2 coats of OPI Rainbow Connection over OPI Black Onyx.
look at it sparkle in the bottle ...
I had been debating as to whether or not to buy Deborah Lippmann's Happy Birthday trio of polishes, so when OPI announced their Muppets Collection I knew I couldn't pass on Rainbow Connection, a glorious blend of cyan, magenta, silver, yellow and green glitters of all sizes. Not an exact dupe for Happy Birthday, but close enough for me.
What colours did you pick up from the Muppets collection?
Which do you prefer? OPI or Deborah?
