Green Version Thumb, Pinky and Middle
Blue Version Pointer and Ring
In terms of formula, the green version was much more opaque, it took 4 thin coats to get this desired opacity from the blue version. I completely love both versions of this polish. Regardless of the reason for OPI releasing a bluer version, whether it be a change of pigment or lax quality control, I am quite happy about it. Both shades are gorgeous and I am happy to own them both.
Do you have either version? Which one do you prefer?
