#49 is a very sheer pinkish jelly base which holds up all those awesome flakes. It really does look great over dark colours, the holographic flakies are so fiery and amazingly transition from red/orange to gold/green, with a hint of purple and even blue mixed in!
I also tried it over lighter pastel colours and orange but didn't really like the effect. It doesn't "pop" in the same way it does over darker colours.
I had to change my usual hand position slightly for the pics so I could capture the full effect of the flakes. Unsurprisingly, I didn't have any sun either but I think the full effect of the polish is still there.
I can see this one featuring in many NoTD's to come!
I then mattified it with Essie Matte About You. I prefer the matte version, you?
