Vava Voom is a magenta / fuschia color between pink and purple. The pic above is in direct sun and the color looks really bright and cheerful. I was actually kind of surprised when I saw the photos because I applied this polish at night and in my mind it was a much darker color. I took another pic in the shade so you can see the difference:
In low light, Vava Voom is a darker berry color. Now that I'm looking at it more closely, it reminds me of China Glaze Designer Satin...I'll have to dig that out from my stash for a comparison sometime.
